Hello,
I've created a ohloh project to get stats about all those bots and
scripts, often based on PWB, that can be found around. For now I added
50.

Please add yours, or those you know of! It only takes a couple clicks.

I know that publishing and listing your code is boring, but the
incentive here is that you get pretty graphs. :)
