The killer app of Facebook, so to speak, is that everybody’s there. Most of us are network with literally everybody we know. That’s an immensely powerful thing, it’s something that’s never been achieved in the history of the internet previously, certainly on any broad level. That’s what somebody else is going to need to crack for Facebook to sink. I think it’s inevitable that that’s going to happen, it’s just a question of when. I used to think that Facebook’s success and time on top would be more terminal than I think it’s proving to be. Facebook could be on top for another 5+ years, which is really an eternity in this industry.
