'Getting rejected from YC is in no way a reflection of the quality of your startup' Yes it is a reflection on quality. They no doubt get it wrong but they have a pretty good track record so it does have some reflection on quality. They are not just randomly picking people.

Facebook and Google didn't go through YC and they seem to have done well. Concentrate on building your business.
