For at least a year now I have been hearing tech pundits say, 'Nobody uses RSS anymore. I just get all my news from twitter.' I have never seen this behavior replicated in anybody I know.

I think that it's because heavy twitter usage has other points of appeal to the tech blogger crowd, most of which are, let's be honest, webcocks. The average internet user, or the average hacker, has no interest whatsoever in following 1-5k twitter users, and no real interest in trying to amass that many users themselves. But the 'social media expert' devotes a large amount of his time and energy to gathering followers, subscribers, commenters, etc., so he has some reason to spend an absurd amount of his time in twitter.
