So I'm in involved with a non profit, takealltypes.org, we have about 50 people who volunteered to help, in reality we have 4 people doing work on it though, its interesting how no matter what type of organization, you start with X and end up with X-10.

I think people like volunteering but not doing any functional work. This is also why most startups stutter, founders dont take things seriously. I am very wary of startups that aren't full time jobs (including my own) as a result of focus. If you want to succeed at a startup you need to be 1000X dedicated and focused or you'll drop the ball.
