They don't contradict my thesis since Tumblr was always much bigger than Posterous and while they may have had faster growth it was never enough to catch up. Again -- I may be proven wrong in six months or a year, and if so I admit it publicly right here (in fact, do you want to make a bet?). But I think at this stage the data warrants the trend I extrapolate from it.
