indeed +Spencer Fleury but I have read a few articles that state that tumblr is taking over the internet and that tumblr activity is on track to eclipse facebook/twitter/gPlus. But is anyone really reading these pages? I must be missing something.
Tumblr is the porn MECCA of a social sites! While Facebook pages has its share too and G+ but get reported and that sucks :( but tumblr is more lenient to that category oh and it has awesome treat photos Lol.
