Ohloh is social website for aimed open source developers. It is also great way to find nice open source projects.

Anyone can add a open source project to Ohloh and then Ohloh uses svn (or git) to download projects source code for analyzing. After analyzing you can see how many lines of code is on example Vim, Firefox or even Linux Kernel. Also smaller projects are analyze not just, major softwares. There is also commit history and cool graphs that show amount of code lines.

There is also social part. Registered users can add information to profile and update a twitter like “journal”. The idea of journal is cool, but it is hard to get every one on project to use it actively.

Ohloh is great website for open source developer. I recommend it for everyone who writes open code and likes web 2.0 websites.
