All my buddies are on Facebook, so I'll stick with it, but I also have Twitter and Tumblr, the're funny, Tumblr it was useful to search for gifs, not that Google Images can find them so easily, **** Tumblr
I never used Twitter before coming to University, but now that Im here I use it a little more. Facebook is still the one I use the most because it is the most useful for organizing social events and stuff like that.
