Yesterday Daniel Nauck showed me Ohloh site.
There was even Npgsql project registered there! I never heard about this site until yesterday. And it is very nice! Thank you, Ricardo Stuven for creating the project. At least this is the person who appears as the project creator on the history page.
From the project page you can see a timeline of commits, code analysis, miniblogs like twitter about development and many other things. Cool!
Thank you very much for the tip, Daniel. I think this site will be a great addition to provide more information about the project to our users and other developers.
