In 2004, the site was re-branded as "Baseball Think Factory" and was re-built on a different software platform in order to support the growing user population and accommodate user registration and content management features.

Site sections

The site features a number of sections with content for different audiences. Some of the more notable ones are:
  • Baseball Newsstand – The newsstand is a newsblog where significant baseball-related articles are linked. Entries usually feature a provocative excerpt of the article along with a discussion thread. For many site members, this newsblog is the "main" part of the site.
  • Hall of Merit (abbreviated as the HoM) – A sub-site conceived by Joe Dimino as an alternative to the National Baseball Hall of Fame in Cooperstown

    . The purpose of the HoM is "to identify the best players in baseball history and thereby identify the omissions and errors that can be found in the other venerable institution." Given the focus of the main site, the discussions often appeal to sabermetric criteria, including in-depth understanding of the various historical eras of major league and negro league baseball as well as advanced statistics.

  • Team Sites – The popularity of some teams has led to the creation of sub-sections of the newsblog that link to articles of interest to specific teams. There currently are four such team blogs: Sox Therapy (Boston Red Sox), Gonfalon Cubs (Chicago Cubs), Count the Rings (New York Yankees), and It's Mets...Just Mets (New York Mets)
  • Game "Chatters" – Specific threads are devoted to regular season and postseason major league baseball games (as well as for special events such as the Olympics or the World Baseball Championship). Site members contribute to the group liveblog during these events.
  • Dialed In and Primate Studies – These sub-sites feature original baseball research and merit a more in-depth discussion below.

Original research

BTF has featured numerous original research articles, primarily under the aforementioned sub-sites "Transaction Oracle," "Dialed In," and "Primate Studies." Several analysts such as Mitchel Lichtman and Tom Tango

 regularly posted original research articles and participated on discussion and criticism of the work at BTF before going on to establish their own sites and to publish results in book form.

Given that statistics characterizing major league offense (batting) are fairly well established, much of the research posted on BTF spotlight defense (fielding) in the form of statistics more accurate than traditional fielding statistics.

Some of the notable examples include:

Mitchel Litchman's articles on UZR (ultimate zone rating)

Litchman has been one on the innovators in the creation of fielding metrics that use play-by-play records that record the location of individual batted balls. Litchman combines this play-by-play data with his linear-weights system that assigns run values to the various baseball plays and their context within the game (inning, runners on base, score, etc.) Some of his initial articles on the system were posted on BTF:

Gomez is a former college and professional pitcher who contributed articles featuring detailed, frame-by-frame analyses of pitcher mechanics. Gomez's analyses were notable in that prior to their publication, the average fan had little access to detailed evaluations of pitchers' mechanics and had to rely on short descriptions gleaned by beat reporters from scouting reports.

Gomez's efforts and innovative articles were rewarded when the Arizona Diamondbacks
