Curiously that closing line is one with which I completely disagree. Someone once described the difference between Facebook and Twitter as "Facebook is for people you used to know, Twitter for people you want to know". Speaking for myself, I get a lot of value from Twitter by following people that are smarter than me, and mostly, I don't really "know" them, and they mostly don't know or follow me back. I don't care for follow-backs, I care to get their wit, their pointers, their knowledge, their humor. For "people you know well" there's meatspace, or Facebook when geography makes the former impractical.
