 at the bottom of the post or content. This makes the content appear in their friends' News feeds. Facebook says "Liking" is intended to "Give positive feedback and connect with things you care about".

A "Like Button" is also available for use on websites outside Facebook: "When the user clicks the Like button on [a] site, a story appears in the user's friends' News Feed with a link back to [the] website." At the same time when any visitor, including non Facebook members and logged out users, visit a site with the Like Button, their presence on the site is recorded by Facebook. Introduced in April 2010, by September 2010 over 350,000 sites had installed it. A "Like Box" also allows Facebook page owners to see how many users and which of their friends like the page.

Messages and Inbox

Since the website's founding, it has allowed users to send messages to each other. A Facebook user can send a message to any number of his/her friends at a time. Deleting a message from one's inbox does not delete it from the inbox of other users, thus disabling a sender to redo a message sent by him or her.

On November 15, 2010, Facebook announced a new "Facebook Messages" service. In a media event that day, CEO Mark Zuckerberg said, "It's true that people will be able to have a @facebook.com email addresses, but it's not email." The launch of such a feature had been anticipated for some time before the announcement, with some calling it a "Gmail killer."

s, and regular messages, and will include privacy settings similar to those of other Facebook services.

Networks, Groups, and Like Pages

Facebook allows different networks and groups which many users can join. It also allows privacy settings on basis of networks. Groups are used for discussions, events, etc. and are a way of enabling a number of people to come together online to share information and discuss specific subjects. They are increasingly used by clubs, companies and public sector organizations to engage with stakeholders - be they members of the public, employees, members, service users, shareholders or customers. A group includes but is not limited to the following: the members who have joined, recent news contents, wall contents, photos, posted items, videos and all associated comments of such items. In this respect, groups are similar to "Like pages" (below) but contain a different set of features. Groups are limited to 300 groups per Facebook customer.

Since October 2010, there are version 0 (legacy) and version 1 (current) groups. Version 1 or "new" groups can contain the name of the group in their URL if the groups emailaddress of the group is set. Groups do not have a RSS feed to export the wall or the member list, such as Pages have, but external services provide such services

A flag which indicates if the group was created prior to launch of the current groups product in October 2010.

Facebook customers can create "Like Pages" which allows fans of an individual, organization, product, service, or concept to join a Facebook fan club. Like Pages look and behave much like a user's personal private profile, with some significant differences. Public Profiles are integrated with Facebook's advertising system, allowing Public Profile owners to easily advertise to Facebook's users. Owners can send updates to their fans, which shows up on their home page. They also have access to insights and analytics of their fan base. Early on, users had the option to "become a fan" of the page until 19 April 2010 when the option was later changed to "like" the page. While an individual with a personal profile can acquire up to 5,000 friends, a "Like Page" can have an unlimited number of "Likers". "Like Pages" can also be customized by adding new Tabs using the Static FBML application. This powerful feature can bring additional functionality to a page such as e-mail collection, specialized content, or a landing page for sales activity. The URLs of "Like Pages" start with http://www.facebook.com/pages... and include the name of the page.

News Feed

On 6 September 2006, Ruchi Sangvhi announced a new home page feature called News Feed. Originally, when users logged into Facebook, they were presented with a customizable version of their own profile. The new layout, by contrast, created an alternative home page in which users saw a constantly updated list of their friends' Facebook activity. News Feed highlights information that includes profile changes, upcoming events, and birthdays, among other updates. This has enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. News Feed also shows conversations taking place between the walls of a user's friends. An integral part of the News Feed interface is the Mini-Feed, a news stream on the user's profile page that shows updates about that user. Unlike in the News Feed, the user can delete events from the Mini-Feed after they appear so that they are no longer visible to profile visitors. In 2011, Facebook updated the News Feed to show top stories and most recent stories in one feed, and the option to highlight stories to make them top stories, as well as to un-highlight stories. In response to users' criticism, Facebook later updated the News feed to allow users to view recent stories first.

Initially, the addition of the News Feed caused some discontent among Facebook users. Many users complained that the News Feed was too cluttered and full of undesired information. Others were concerned that the News Feed made it too easy for other people to track activities like changes in relationship status, events, and conversations with other users. This tracking is often casually referred to as "Facebook-Stalking." In response to this dissatisfaction, creator Mark Zuckerberg issued an apology for the site's failure to include appropriate customizable privacy features. Thereafter, users were able to control what types of information were shared automatically with friends. Currently, users may prevent friends from seeing updates about several types of especially private activities, although other events are not customizable in this way.
With the introduction of the "New Facebook" - in early February 2010 - came a total redesign of the pages, several new features and changes to News Feeds. On their personal Feeds (now integrated with Walls), users were given the option of removing updates from any application as well as choosing the size they show up on the page. Furthermore, the community feed (containing recent actions by the user's friends) contained options to instantly select whether to hear more or less about certain friends or applications.

Notifications

Notifications of the more important events, for example, someone sharing a link on the user's wall or commenting on a post the user previously commented on, briefly appear for a few seconds in the bottom left as a popup message (if the user is online), and a red counter is updated on the toolbar at the top, thus allowing the user to keep track of all the most recent notifications.

Phone

On September 2010, rumors of a "Facebook Phone" similar to Google's Android, circulated in business and tech industry news. In an interview with well-known technology blog Techcrunch

TechCrunch is a web publication that offers technology news and analysis, as well as profiling of startup companies, products, and websites. It was founded by Michael Arrington in 2005, and was first published on June 11, 2005....

, CEO Mark Zuckerberg was noted to have said, "Our strategy is very horizontal. We're trying to build a social layer for everything," while denying that they were attempting to compete with the Apple iPhone or Android.

Photos

On April 11, 2011, Facebook launched a new feature for photo tagging - people can tag photos with a brand, product, company or person’s Facebook page, similar to the way they tag their friends in photos. In August 2011, Facebook announced that it would be adding a series of photo filters to its mobile application. Facebook plans to unveil nearly a dozen photo filters, which will be similar to Instragram's grainy images. Per last known numbers, today in the world, highest number of photos are hosted at Facebook. Unfortunately, as of yet, Facebook has not tied up with any photo printing companies to offer printed personalized gifts of the photos the users own. Though, there are companies that have modified their websites (example: smugmug.com) to fetch Facebook photos into your account to create a gift. A few applications have come up with unique way of offering an application on Facebook itself to create a personalized gift with Facebook photo (e.g. ezsnaps.com)

Poke

The poke feature is intended to be a poke gesture (similar to "nudge" in instant messaging) to attract the attention of another user. Many Facebook users use this feature to attract attention or say "hello" to their friends. A previous version of Facebook's FAQ gave additional insight into the origin of the feature, stating: "When we created the poke, we thought it would be cool to have a feature without any specific purpose. People interpret the poke in many different ways, and we encourage you to come up with your own meanings." Mark Zuckerberg

There are several applications on Facebook which extend the idea of the poke feature by allowing users to perform other actions to their friends—such as "kick" or "wave to". People often reciprocate pokes back and forth until one side gives up, an event known as a "Poke War".

Status updates

Facebook has a feature called "status updates" (also referred to simply as "status") which allows users to post messages for all their friends to read. In turn, friends can respond with their own comments, and also press the "Like" button to show that they enjoyed reading it. A user's most recent status update appears on the user's wall, and is also noted in the "Recently updated" section of a user's friend list. Originally, the purpose of the feature was to allow users to inform their friends of their current "status" (for example, their current feelings, whereabouts, or actions) by referring to themselves in the third person (for example, "George is happy" or "John is with Robert at his house"). However, users are no longer required to write in the third person. Facebook originally prompted the status update with "Username is..." and Facebook users filled in the rest. This feature first became available in September 2006. However, on December 13, 2007, the requirement to start a status update with is was removed. The question "What are you doing right now?" was introduced. In March 2009, the status update question was changed from "What are you doing right now?" to "What's on your mind?" In 2009, Facebook added the feature to tag certain friends (or groups, etc.) within one's status update by adding an @ character before their name, turning the friend's name into a link to their profile and including the message on the friend's wall. Now, however, typing a friends name without any symbol beforehand will present you with a list of names matching the letters you inputted. This means that the "@" symbol is no longer needed.

Ticker

In 2011, Facebook launched a ticker that showed all of their friends and pages updates. For example, it shows when their friends comment or like a status, and their status updates as soon as they posted them. If users do not have the chat sidebar open, the ticker appears on Facebook home next to the News Feed. If users do have the chat sidebar open, the ticker appears above the list of friends, and can be re-sized (it can't be if the chat sidebar isn't open). The ticker cannot be closed, and this has brought up concern among users, especially privacy concerns. However, Facebook has been keen to emphasize that the ticker only shows what people could see before - it just makes it "more discoverable".

URL shortener

On December 14, 2009, Facebook launched its own URL shortener based on FB.me domain name. From that point on, all links based on facebook.com can be accessed after fb.me, which is seven characters shorter.

Usernames

Starting June 13, 2009, Facebook introduced a feature that allowed users to choose a Facebook username to make user location easier. The user is able to direct others to their page through a simple link such as www.facebook.com/username rather than an otherwise complex URL. This feature on Facebook quickly spread, with more than 1 million users registering usernames in the first three hours. Usernames are now available to any existing or newly registered user.

According to the FAQ, "Facebook reserves the right to remove and/or reclaim any username at any time for any reason".

Wall

The Wall is a space on each user's profile page that allows friends to post messages for the user to see while displaying the time and date the message was written. One user's Wall is visible to anyone with the ability to see his or her full profile, and different users' Wall posts show up in an individual's News Feed. Many users use their friends' Walls for leaving short, temporal notes. More private discourse is saved for messages, which are sent to a user's inbox, and are visible only to the sender and recipient(s) of the message, much like email

Electronic mail, commonly known as email or e-mail, is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the...

.

In July 2007, Facebook allowed users to post attachments to the Wall, whereas previously the Wall was limited to text only. In May 2008, the Wall-to-Wall for each profile was limited to only 40 posts. Recently Facebook has allowed users to insert html code in boxes attached to the wall via apps like Static FBML which has allowed marketers to track use of their fan pages with Google Analytics.

Questions

On March 24, 2011, Facebook announced that its new product - Facebook Questions - facilitates short, poll-like answers in addition to long-form responses, and also links directly to relevant items in Facebook's directory of "fan pages."

Events

Facebook events are a way for members to let friends know about upcoming events in their community and to organize social gatherings. Events require an event name, network, host name, event type, start time, location, and a guest list of friends invited. Events can be Public or Private. Private events cannot be found in searches and are by invitation only. People who have not been invited cannot view a Private event's description, Wall or photos. They also will not see any Feed stories about the event. When setting up an event the user can choose to allow friends to upload photos or videos. Note that unlike real world events, all events are treated as separate entities (when the reality is some events sit inside other events, going to one event would preclude going to another, and so on).

In February 2011, Facebook began to use the hCalendar microformat

 for the events' venues, enabling the extraction of details to users' own calendar or mapping applications.

Marketplace

In May 2007, Facebook introduced the Facebook Marketplace allowing users to post free classified ads within the following categories: For Sale, Housing, Jobs, and Other. Ads can be posted in either available or wanted format. The market place is available for all Facebook users and is currently free. In 2009, Facebook transferred ownership of the Marketplace to Oodle.

Places

Facebook announced Places on August 18, 2010. It is a feature that lets users "check in" to Facebook using a mobile device to let a user's friends know where they are at the moment. This feature is already known from Foursquare, a social network where users share their geolocation data via mobile phones.

In November 2010, Facebook announced "Deals", a subset of the Places offering, which allows for users to check in from restaurants, supermarkets, bars, and coffee shops using an app on a mobile device and then be rewarded discounts, coupons, and free merchandise. This feature is marketed as a digital version of a loyalty card

Discontinuation: Facebook Places was reported discontinued on August 24, 2011.

Platform

The Facebook Platform provides a set of APIs and tools which enable third-party developers to integrate with the "open graph" — whether through applications on Facebook.com or external websites and devices. Launched on May 24, 2007, Facebook Platform has evolved from enabling development just on Facebook.com to one also supporting integration across the web and devices.

Facebook Platform Statistics as of May 2010:
  • More than one million developers and entrepreneurs from more than 180 countries
  • More than 550,000 active applications currently on Facebook Platform
  • Every month, more than 70% of Facebook users engage with Platform applications
  • More than 250,000 websites have integrated with Facebook Platform
  • More than 100 million Facebook users engage with Facebook on external websites every month


Third party companies such as Adonomics, Kontagent and Mixpanel provide application metrics, and blogs such as AppRate, Inside Facebook, and Face Reviews have sprung up in response to the clamor for Facebook applications. On July 4, 2007, Altura Ventures announced the "Altura 1 Facebook Investment Fund," becoming the world's first Facebook-only venture capital firm.

On August 29, 2007, Facebook changed the way in which the popularity of applications is measured, to give attention to the more engaging applications, following criticism that ranking applications only by the number of people who had installed the application was giving an advantage to the highly viral, yet useless applications. Tech blog Valleywag has criticized Facebook Applications, labeling them a "cornucopia of uselessness."[5] Others have called for limiting third-party applications so the Facebook "user experience" is not degraded.

Primarily attempting to create viral applications is a method that has certainly been employed by numerous Facebook application developers. Stanford University even offered a class in the Fall of 2007, entitled, Computer Science (CS) 377W: "Create Engaging Web Applications Using Metrics and Learning on Facebook". Numerous applications created by the class were highly successful, and ranked amongst the top Facebook applications, with some achieving over 3.5 million users in a month.

Questions

In May 2010, Facebook began testing Questions. Questions is an application in which users submit questions for their friends to answer. It is expected to compete directly with services such as Yahoo! Answers

Photos

One of the most popular applications on Facebook is the Photos application, where users can upload albums of photos, tag friends helped by face recognition technology, and comment on photos. According to Facebook,
  • 50+ billion user photos (in July 2010)
  • More than 1.5 petabyte

  • 220 million photos added each week which take up 25 terabytes of disk space (in May 2009).
  • 3+ billion photo images served to users every day (in May 2007).
  • 550,000+ images served per second during peak traffic windows (in May 2009).

Videos

During the time that Facebook released its platform, it also released an application of its own for sharing videos on Facebook. Users can add their videos with the service by uploading video, adding video through Facebook Mobile, and using a webcam recording feature. Additionally, users can "tag" their friends in videos they add much like the way users can tag their friends in photos, except the location of the friend in the video is not displayed. Users also have the option of video messaging. Videos cannot be placed in categories, whereas photos are sorted by albums. Facebook Video can support up to 1080p format and even 4K resolution.

Security features

On May 12, 2011, Facebook announced that it is launching several new security features designed to protect users from malware and from getting their accounts hijacked.

Clickjacking warnings

Facebook will display warnings when users are about to be duped by clickjacking and cross-site scripting attacks in which they think they are following a link to an interesting news story or taking action to see a video and instead end up spamming their friends.

Login Approvals

Facebook also offers two-factor authentication called "Login Approvals," which, if turned on, will require users to enter a code whenever they log into the site from a new or unrecognized device. The code is sent via text message to the user's mobile phone.

Site warnings

Facebook is partnering with the free Web of Trust safe surfing service to give Facebook users more information about the sites they are linking to from the social network. When a user clicks on a potentially malicious link, a warning box will appear that gives more information about why the site might be dangerous. The user can either ignore the warning or go back to the previous page.

FBML

Facebook Markup Language (FBML) is considered to be Facebook's own version of HTML. While many of the tags of HTML can be used in FBML, there are also important tags that cannot be used such as HTML, HEAD and BODY. Also, Javascript
JavaScript
JavaScript is a prototype-based scripting language that is dynamic, weakly typed and has first-class functions. It is a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles....

 cannot be used with FBML.

According to the Facebook Markup Language (FBML) Developer's page, FBML is now deprecated. No new features will be added to FBML and developers are recommended to develop new applications utilizing HTML, JavaScript and CSS. FBML support will end January 1, 2012 and FBML will no longer function as of June 1, 2012.

Gifts

In February 2007, Facebook added a new virtual gift

 feature to the website. Friends could send gifts, small icons of novelty items designed by former Apple designer Susan Kare

, to each other by selecting one from Facebook's virtual gift shop and adding a message. Gifts given to a user appear on the recipient's wall with the giver's message, unless the giver decided to give the gift privately, in which case the giver's name and message is not displayed to other users. Additionally, all gifts (including private gifts) received by a user are displayed in the recipient's gift box (right above their wall on their profile), marked with either the first name
Given name
A given name, in Western contexts often referred to as a first name, is a personal name that specifies and differentiates between members of a group of individuals, especially in a family, all of whose members usually share the same family name...

 of the user (for public gifts) or the word "Private." An Anonymous option is also available, by which anyone with profile access can see the gift, but only the recipient sees the message. None will see the giver's name, and the gift goes in the recipient's gift box but not the wall.

Facebook users are given one free gift to give upon registering their account. Each additional gift given by a user costs US$1.00. The initial selection of gifts was Valentine's Day
Valentine's Day
Saint Valentine's Day, commonly shortened to Valentine's Day, is an annual commemoration held on February 14 celebrating love and affection between intimate companions. The day is named after one or more early Christian martyrs named Saint Valentine, and was established by Pope Gelasius I in 496...

 themed, and 50% of the net proceeds (after credit card processing fees were taken out, etc.) received through February 2007 were donated to the charity Susan G. Komen for the Cure
Susan G. Komen for the Cure
Susan G. Komen for the Cure, formerly known as The Susan G. Komen Breast Cancer Foundation, often referred to as simply Komen, is the most widely known, largest and best-funded breast cancer organization in the US....

. After the month of February, the proceeds were no longer donated. Soon after, Facebook began making one new gift available each day, most of which had a limited supply or were available for a limited time.

On 8 November 2008, Facebook changed the $1.00 per gift model to a micro-payment model of 100 points per $1.00, with the existing gifts costing 100 points. They planned to allow a wider variety of gifts in the future.

The built-in Gifts feature was removed on August 1, 2010, to allow Facebook to focus on more important website features. Existing gift-giving applications can be used as a replacement for the Gifts feature.

Lite

In August 2009, Facebook announced the rollout of a "lite" version of the site, optimized for users on slower or intermittent Internet connections. Facebook Lite offered fewer services, excluded most third-party applications and required less bandwidth. A beta version of the slimmed-down interface was released first to invited testers before a broader rollout across users in the United States, Canada, and India. It was announced on 20 April 2010 that support for the "lite" service had ended and that users would be redirected back to the normal, full content, Facebook website. The service was operational for only eight months.
