i'm not sure how contrasting ubuntu with gnome3 is really a rebuttal, when gnome3 gets almost all the same criticisms that ubuntu does. the bloggers start frothing at the mouth every time gnome3 introduces a change the same way that they do when ubuntu introduces a change. gnome3 is progressing as rapidly as they are precisely because project leaders are exercising exactly the same sort of unilateral decision making process that canonical is.
