Having raised cap and interacted with a bunch of YC alums (hired 2 and friends with others), I can strongly second Elad's points. Just because they're in YC and exposed to some very accomplished people doesn't imply that they already know these things. They have a lot to think about when they're starting up their companies, so it's hard for them to absorb everything at once, despite being super smart.
