I don't know this guy. I can't vouch for his credibility. But, I'd like to know the if what he says can actually be proven.

With the advent of MySpace, Facebook, YouTube, Imeem and the flock, things are a changing.  I work for an internet measurement company with a focus on competitive intelligence so I am lucky enough to scope the evolution of the internet in real time.  It's not uncommon to see a website's traffic be 20-50% from search (google, yahoo, msn, live, mamma, etc.)  However, more and more the social networking community space is often times contributing the same if not more of a websites traffic. 

I guess I should just ask, huh?
