A suite of tools used to help surface interesting and popular stories as well as improve WordPress' CMS capabilities as an application platform.
Lies, damn lies, and statistics. I have yet to see any two stats gathering mechanisms report the same numbers. The code is GPL'd and I welcome suggestions for improvements.
bStat's primary features are to offer information to your readers about what stories are popular and help illustrate those trends to blog authors. I leave it up to blog administrators to decide if the mechanism bSuite uses to get that data is sufficient to the purpose, though I will add that I run a number of stats applications in addition to bStat (Google Analytics and AWstats).
