Happy? Sad? Disgusted?
Nat Pryce wrote a program to find out how developers feel about their projects. He extracts code comments and feeds them into Synesketch. Nat has even posted results from a number of different open source (and a couple nameless closed source) projects.
I find it really interesting. I wonder if it truly correlates to the health of the project or the morale of the project team.
