OK, I joined ohloh. (It must be getting hard to come up with a name that Google has nothing else to say about.) Ohloh will be more interesting when they learn to count better; maybe Google will buy them and fix that and make it faster. In the meantime it's kind of fun. My only serious gripe is that they conflate C++ and C code together as "C/C++"; "Java/C#" as one entry would make more sense. Maybe the best thing about it, so far, is the map: when you tell it where you live, it shows markers for other Free Software people nearby. It will get better as more people join. That would be fun to have in Advogato.
