Well google clearly wants to get away from backlinks as a ranking factor - I accept that, but if Panda is all about Exit rates how does someone using amazons mechanical turk to generate good data figure?

Also where exactly does this data come from, not analytics, perhaps they buy ISP click data, chrome is the obvious answer but reading Cutt's description of what they actually collect [mattcutts.com ] I doubt it.
