Time spent on Facebook passed all Google sites in September 2010 (including YouTube), yet Google will capture 44% of 2011 online spending, Facebook will only get 8% , because of the impact of search.

And it briefly draws on basic economic theory. So unless you like rants based on forgotten college coursework, use the navigation or category links above to find another post. Look at Google and Facebook.
