The Times Online has a list of the top 20 Twitterers in fashion and style. (I'm not one of them--maybe next year.) Seems like a decent list, although in checking out the streams it becomes more obvious how limited this particular technology is in getting across the sheer exhilaration of style--there's an extra step between you and the visual element. (Not to mention how prone it is to the lazy practice of name-dropping.) I'm also somewhat surprised they included French Vogue on the list, given that (at the time of this writing) they haven't tweeted since October. But they're French--they can get away with it.
