I think it is astounding that Arrington (and everyone else on the team -- I'm sure there are many) was able to pull this off. A lot of people have bones to pick with him, and he can certainly be a little brusque (speaking as a former TechCrunch intern), but he is one incredibly capable guy -- a consistently excellent writer, bitingly funny commentator, and, apparently, a mean product designer/manager. I almost wish TechCrunch didn't take up so much of his time -- there's probably a lot more he could be doing.
