From Al Roth’s Market Design blog:

Mathoverflow.net is an internet site on which people can ask and answer math questions. It elicits a good deal of effort for free, in an Open Science, reputation-mediated way.

It has a reputation system, based on the votes “up” your questions and answers get. Other users can alsoreduce your reputation by 2 points, at a cost of 1 point to themselves, if they don’t like your posts.

There’s also a set of distinctions that users can earn, called badges.
