That's a good point, and I agree that it's highly unlikely that anyone will have the time or resources to execute an idea I share with them. I would hope that they get excited about the idea though, to the point where they wish they could do it themselves.

I guess what I'm getting out of this is "don't worry about it". I think that as long as I don't go pitching the ideas to a competitor, I'll probably be okay. I guess it also can't hurt to keep developing a little bit more before pitching an idea, so that I have something concrete to show.
