Rocketboom, the 800 pound guerrilla of vidcasts, has gone down. At first it just went down with archives showing and indicated that a vacation was in progress. Then the star, Amanda Congdon, announced that she had been canned (video) and published the last written correspondence before the producer stopped putting anything in writing.
The producer is promising to be back up in a few days. Should be interesting since Congdon still owns 49% (wonder if there are any profits forthcoming) and the entire show has basically been a cult of personality (see AC's picture on 90% of the archives). I never was the biggest fan of Rocketboom (I found about one in three funny), but it was pretty clear that the massive success it had was dependent upon AC.
