StackOverflow now makes this data freely available and some people have done extensive analysis. <a href="http://brianbondy.com/blog/id/105/twitter-accounts-for-all-stackoverflow-users-by-reputation" rel="nofollow">Brian Bondy</a> has analyzed the StackOverflow data to report reputation scores for users who have Twitter accounts. Maybe he has done other analysis. I haven’t done any more with this, but some people have. StackOverflow now makes this data freely available and some people have done extensive analysis.

If you invert the first graph you can see a classic <a href="http://en.wikipedia.org/wiki/The_Long_Tail" rel="nofollow">Long Tail</a> distribution, with many users whose questions and answers on the site are generating relatively few up votes (non-hits in Long Tail parlance). I'm not sure the publicly available data can tell us the whole story, though. I wonder if there's an invisible group of users who are relatively inactive in asking and answering questions, but who are very active in voting for questions and answers. If so, the Long Tail users are having a bigger impact on the site than is apparent from the publicly available data.
