The rise of Quora has surprised me. It is quite a good service, though not quite as good as Stack Overflow, which is still the best. Still, it has bypassed Stack Exchange, or will bypass it in the near future (in my opinion; correct me if I'm wrong).
Basically, getting mentioned in popular blogs and attracting many people whom other users would like to follow did the trick for Quora.
My question is, now that SE is in place and running nicely, wouldn't it be helpful to make it more popular by marketing rather than pure natural growth? That way, more people would use it and there would be better overall knowledge sharing.
Also, wouldn't it be nice to have follower/following links? In other words, to inject a little bit of social networking; that's what Quora is doing.
