Exactly! When I see all the hand wringing around twitter, I'm surprised how rarely it's mentioned that the natural market size for twitter is just much smaller than Facebook's. My theory is that there is basically a personality divide, probably along the introvert/extravert divide, among those who like twitter, and those who don't. Thus, those who like and use twitter frequently blame all its problems on technical details, because they can't grasp that those who don't FUNDAMENTALLY have an aversion to the push model of 140 char limited thoughts. I look at twitter and think "Random short distractions are things I'm actively trying to remove from my life."
