Lately I was wondering whether BioStar is losing its appeal or if it is rather a subjective impression I am having about BioStar. My question: is the BioStar fading?
My own objective stab at this can be found here: http://joachimbaran.wordpress.com/2011/03/07/biostar-fading/
UPDATE (March 2012): I have redone the analysis and posted the results as "BioStar: Is the BioStar fading? An Annual Follow-Up." http://joachimbaran.wordpress.com/2012/03/11/biostar-second-analysis/
UPDATE (March 2013): This year I have added more charts to my analysis and posted the results again on my blog as "Uh-oh, Biostar: Three Years of User Metrics Analysis" http://joachimbaran.wordpress.com/2013/03/15/uh-oh-biostar/
UPDATE (March 2013, follow up to criticism): It has been pointed out that I include too many other post types besides questions/answers, which influences my analysis and statistics. Having also taken input from the Biostar API now, I re-ran the data mining script and it turns out that the web-crawler already ignores non-question posts. There are only 36 data points for "Forum" (type id 6) Biostar posts, but about 47000 question/answer related data points. In other words: the new Planet or blog posts on Biostar do not influence my analysis.
UPDATE (April 2014): The fourth annual analysis has been posted. It is the first time that I incorporated data from the Biostar RESTful API. See: "Analyzing the Biostar: Fourth Anniversary" http://joachimbaran.wordpress.com/2014/04/08/biostar_analysis_4th_year/
