Isn't that "90%" figure pretty commonly bandied around about startups in general?

Seems to me this is pretty much saying TechCrunch just covers a random sampling of startups, and provides zero benefit to the ones it covers. (A more cynical view might be that if it's true that TechCrunch provides some benefit for some of the companies it covers, it must provide _negative_ benefit for the rest to maintain it's same-as-random-sample average…)
