Use twitter how you want to use it, and how you get the most value out of it. Follow people whose tweets you enjoy reading. Can't we just leave it at that? Leave the rest of the twitter over-analyzing to TC, they certainly do enough of it.
That doesn't reduce the value of email for those that are received by people though.
