Actually, I think this is the most important part of the process. When you're small you have the luxury of making mistakes and no one cares. When you wield some power/prestige and your actions affect other peoples' lives, people start coming to you with grievances.

That doesn't mean that YC is failing, just that the problem is really hard.
