Scott Dalton has a list of Boston fans on Twitter, obviously it's not exhaustive but it's not bad.
@scottydalton/boston-fans is the list name.
Aggy: It's difficult to explain, you either get it or you don't. It's not so much about knowing the minutiae of peoples life more about being connected to a network where you can read how current events are influencing people as they happen. It forms a time-line of current events and the opinions people form on those events as they happen. This has never been possible before and provides an excellent opportunity for social experiment.
