* There's value in just seeing a list of ideas to help with brainstorming.
I think that this will lead to more startups being started, which is a good thing. It'll help people who don't start one because they don't have an idea. And it'll lead to some pretty good ones being started because the wisdom of the crowd will produce some good ideas.
Whether or not this succeeds depends on the community of users. HN has the perfect community for this. Thus, I propose that an "ideas section" be added to HN where you could add and vote on problems and startup ideas.
