facebook vs. twitter

I found this breakdown of demographics for 2010 at http://pronetworkbuild.blogspot.com/p/facebook-vs.html (very interesting site if you are into social media/social marketing) – even though the numbers have changed dramatically in 2011 (facebook at 800 million, twitter at 200 million users) I think it is still interesting and valid.

Especially the fact that many users follow brands using facebook or twitter and actually are inclined to buy from these brands is something I did not expect at this level.
