This is interesting, but I'm not sure if it's really saying anything more than: Quora, as a knowledge-store, can power mobile search. I say mobile search, since that seems to be the implication of his dream of a siri-quora collaboration.

But is knowledge extraction from Quora really so game-changing with respect to the mobile web? Don't get me wrong--I love Quora and I think it's an incredible knowledge resource online.

But I think the power of siri comes from real-time knowledge (that is, knowledge or information that is useful to us while we're on the go). My experience on Quora has been so much more about intelligent, high-quality content than about real-time, practical, in-the-moment information.
