There are more applicants than YCombinator could accept (or anyone could accept if you look at it in scale). Someone should create a social-media type website for YCombinator applicants (or anyone) to share their stories, meet, interact, network, learn, and collaborate on new and existing ideas. Imagine how many start-ups would be "born" like this. Think of how many great ideas don't get in or simply don't apply, think of how BIG this community could grow to be in a short time - it would grow by itself. Look at what Kickstarter is doing. Think of how many new comers this type of stepping stone would benefit and help achieve their ideas. Starting this community is possible by creating a great website that creatively engages members to collaborate. Let YCombinator (and anyone else) endorse it - first to members of the y-community then others. In fact "y-community" should be the name of it. We all know that out kind already burn with passion, desire and creativity. With minimal guidance from YCombinator it could succeed faster - passionate desires of those not-accepted will continue to burn and be fostered. Eventually, and this is speculating perhaps, if YCombinator becomes somewhat involved, with so many start-up communities popping-up in every city and country, this website, could grow to become the "Facebook" of start-ups. (only it would also be productive :) But seriously.
