just to clarify, twitter mods can and often do, shut down peoples threads for different reasons.... the obvious ones, harrasment, things like that.., i doubt we'll ever know who did this one for sure..
i love twitter, a great place to throw out random thoughts, silly stuff, chat instantly with people all over the world, for free..!! and as you say, some celebs are great, theres also great instant info...
i follow ashton kutcher, who tonight posted a video saying how amazed he was that he was nealry at 1 million followers, how that just blew him away, especially the cnn is only 50,000 more than he.. he cant understand it, so he says, "if i get 1 mil followers before cnn, i will personally video and ding dong ditch ted turners house"..
ashton tweets all kinds of info, funny stuff, pics and vids of the current film he's making..
i find twitter facinating, it just needs to be used with discretion..
facebook, has changed over the last few months, and for me, not a great change....too many trivia quizzez, and not enough ways to edit some of that out, its either all or none..posts dont seem instant either, they get lost on walls.. its just not obviously clear and in your face, as twitter is..but..to each his own..
