EFV,
I didn't mean to say that UGC can replace authority informative sites, I was saying that traffic critical mass from Web 2.0 new community or verticals like WW should not be underestimated in its power to mutate and sprout other successful verticals, who in turn are born giants from day one, those offsprings are the ones capable of replacing or at least hurting the market share of well established giants, probably explains Google's recent products fertility, which can be seen as a preemptive move.
