How about we set up a seasonal voting mechanism, that allows us to track who of us were rejected, and who of the rejects we consider the very best - a true gem that YC missed.
I think the time would be better spent working on implementing the idea and winning. Once you win, you can stick your tongue out at YC as much as you want. :-)
I'm currently working on a site to help anyone who was rejected from YC (the YNot's), and anyone else, a place to collaborate, find a co-founder, and assist those looking to move to SV. I was also planning on adding a section so people could demo their startup, have them voted on, and receive feedback. Nothing badmouthing YC, but just a place to keep rejected spirits up and give them some incentive to continue working on their startups.
I don't understand this reluctance to share an idea for a startup. It's ridiculous, because it seems to be predicated upon the assumptions that no one has thought of it, and if they did they would go off and immediately implement it. What arrogance. You could tell them every little detail of what you have and mind and, because language is so vague, they could think it was something entirely different.
If you tell me about your startup, your first goal, before you can make me a user or (even better) a paying user, is to get me to give a shit about it, which is a formidable task.
