I'm not necessarily sure why anybody in their right mind would create such a thing and share it! Ideas are less valuable than execution, but ideas are valuable nonetheless!
People should really be solving their own painful problems anyway (always better to be your own customer!) whose solutions can in some way be successfully and profitably exchanged for money.

Best startup ideas are about solving real problems. Some people care about problems getting solved, whether or not they are the ones doing the solving. Keep in mind that no one has enough time to try and solve all the problems at once. So if you see something wrong that needs to be fixed, and you don't have time to do it yourself (because you're busy fixing something else), why not just share it with people, so that someone else might work on it, thus helping to make our world a better place?
That's reasonable however I've always been of the opinion that it's better to solve a problem when you have the problem and are feeling the pain, rather than implementing someone's idea in the abstract. It always seems that the people who are really solving their own painful problems capture a market.
Maybe other people are better at implementing someone else's idea than me and I'm just viewing the world through Matt-colored glasses.
