Ohh, and one more thing. Maybe I missed it, how many applications did you/YC receive for S14 batch? I've read on Sam's blog that it was around 20% more than in the previous edition, but would be great to know the exact number ...
We've also got rejected, and now I'm pretty sure that Ycombinator is just a great bottleneck itself. It can even be inferred from Kirsty's email or Sam's post: http://blog.samaltman.com/the-worst-part-of-yc.
Anyway, it's now like a challenge for all of the good/promising startups (including ours) to prove them their mistakes or missed opportunities resulting from undercapacity. On the other hand, I wish all the best to every accepted company! You're now on a better track to your success ;)
