I have been using twitter for a few days now, and it really is a weird mix of broadcasting, SMS, blogging, and “shouting into a general direction”. In other words: It is fun, it is hard to understand why people do it, and all uses for it that are somehow justifying doing it are great ones like “when an earthquake strikes I can tell everybody quickly!”. Well. This is the first thing I would do when an earthquake hits me, too.
Still, it is fun, and for me it replaces my skype status text. If everyone of my friends was using it, even better - until then I am following what Leo Laporte, Merlin Mann and Scoble (who is cheating;-> ) are twittering. Gosh, it feels a bit like legal stalking
