Sad, go back and read the second half of the first paragraph of the email you received. Do you realize the odds of getting into Harvard are better then getting an interview with YC and even then only about a third are accepted. Not having an extra 15K in the bank never stopped anyone from launching a startup.
I bet that more startups are started because of groups applying to YC. It's a good thing you applied, but move on already. My partner and I don't need the money. We applied more for the mentoring and camaraderie one gets spending time in a group setting. Instead of YC we're tapping the locals here in NYC, online and anyone else we can think of to bounce ideas off of, test our application and help get the word out once we've launched.
Go, work, launch. Let me know when you do.
