Few months ago I read reports of
Facebook to surpass
Google -maybe- by 2012 or 2013. My gutt feeling - it will happen in the next 120 days.

Imagine a community website taking leadership of the WWW - yet this is happening as you read those lines.
Facebook is growing fast +220% this year reaching 122M uniques in July.
Google leads with 147M uniques BUT it is absolutely inevitable
Facebook will win this battle.
Google is facing serious attacks from
Microsoft with
Bing.com.
Yahoo! has remained solid behind Google despite the Ballmer/Chen fiasco. Google's numbers are stable but no real sign of growth despite a rise in search queries.
Facebook has doubled its uniques from 66M in January 09 to 122M in July 09 and I see a peak of uniques starting right after summer holidays. Millions of pictures are going to be posted to Facebook. There is one ironical fact: 1st source of incoming traffic on Facebook is....Google. Maybe Google will react to that and start pushing Facebook results a bit further down.
FaceBook will be #1 site in the world by December 09. INCREDIBLE.
