- #23 As his animated map shows, over the last few years Facebook has cut down the number of top social networks around the world from 17 to just six. More specifically, there were 17 in June 2009, 16 in December 2009, 14 in June 2010, 11 in December 2010, nine in June 2011, and six in December 2011. Here are the remaining six: Facebook, QZone, V Kontakte, Odnoklassniki,Drauglem, and Zing. Between June 2011 and December 2011, Facebook managed to conquer Netherlands, and with it the whole Europe, Brazil, after a long struggle to overtake Google's Orkut, as well as Japan (although a large part of Japanese networking activities are on mobile, including Gree, Mobage, and Mixi). If you remember that Facebook is still banned in many countries, such as China (the world's largest Internet population with 500 million people), the service's dominance is certainly impressive. If this trend continues, it won't be long before the social network is king in all the countries it can be accessed in.

- #30 Pew found that 55% of online teens have profiles, 66% of whom report that their profile is not visible to all Internet users (Lenhart & Madden, 2007). Of the teens with completely open profiles, 46% reported including at least some false information.
