I'll go ahead and make some suggestions: like dlf said, it would be nice to be able to play with it before registering. Furthermore, you should allow the user to login with OpenID services such as Google or Facebook, anything you can do to reduce the time it takes for a user to get started. You should add an easy way to edit the idea once it has been made. I frequently want to revise or add some resources that go along with an idea I may have. It's a good start, but lacking some features that would prevent me from using it as a way to store my ideas primarily. I'd be interested in hearing about your progress, it's going to make for a great learning experience.
