I think everyone agrees that coming up with ideas is pretty easy (not to mention fun). Personally though, as soon as I do a bit more thinking about any idea, I realize how much work it is to make the idea a reality. Some of this work makes sense to me - the coding part. I have written code before. I can approximate the effort required (knowing my estimate is wrong, of course). The other part of the effort - marketing, getting users, convincing investors, other things I can't even think of - is an unknown to me. I have never done anything like it. This is how you'd convince me to join your project: by convincing me you can take care of that other stuff I don't know much about. I think a team with complementary skills can work. But it has to be more or less an equal partnership. What will scare me off is the impression that I will be implementing someone's vague and constantly changing idea with no credit for my work.
