One of the things that might be bad about this is competition. If I'm trying to start a startup and I've noticed a common problem and there's zero competition for solutions - that would be the ideal scenario for a new startup. But a service like this could have multiple people inadvertently working on duplicate solutions for the same problem. There is no mutex.

Don't get me wrong its a cool idea but probably nothing will beat basic observation and creative thinking when it comes to finding new ideas.

That's true multiple people could be working on the same problem, but I'd counter with two points. One, MySpace came first and solved a similar problem to Facebook, yet two totally different outcomes - execution is key. And two, I think the cool thing about sending problems not "business ideas" is that one problem statement could yield a thousand different solutions.

Most ideas there already have some competition.
