ha-ha!
that Mayer one is priceless.
mind you he strikes me as not the nicest fellow, didn't he treat Aniston pretty shabbily by most accounts?
i got on Twitter yesterday purely re Iran (i am under no illusions about a 'twitter revolution' obviously).
i appreciate some people who have e.g. emotional issues might find Twitter a worthy foil to put down seemingly mundane observations that are in fact a conduit/cathartic cover of sorts, for far more serious matters, and i appreciate it's good for musicians, DJs etc (in fact i'm now following Zhao

), but in general i can also see why there is the cynicism.
Blogger and Wordpress etc allow far longer pieces so,
analysis, teased-out views, not just the 140 character limit, and at least tumblr allows you to embed photographs and such.
