it sounds like a wise strategic decision by facebook. since it's likely there would be YC startups which address facebook deficiencies and eat away at their marketshare. although it looks impossible for any challenge to facebooks position, all it takes is one huge outlier which could change the game, and YC seems like a probable source of such an outlier. but for YC startups it seems like a tradeoff.... short-term boost at the expense of long-term dominance.. but i don't know the details of the deal so can't be sure.
