I kind of like assembly.com because you can find a group of people to contribute. I just wish there was a way to try and recruit to the project. Like interest, skills section. I have a domain name: bountysplit.com that could be used for recruiting. even just in the jobs market. it's on assembly.com with couple of my ideas. I'm a developer so I don't have the get something built problem. I have the getting traction problem.
