Besides the normal Blogger, Facebook, Twitter, here are a few that I frequent.
reddit (all things funny and awesome)
lolcats (the cutest/funniest kitteh pictures ever)
Pinterest (a virtual cork-board of everything that is classy/trendy/beautiful)
Taste Spotting (pictures (and recipes) of yummy food)
New York Times (where I get the news)
Hyperbole and a Half (the funniest blog you will ever read. ever.)
What are some of your favorite sites?
p.s. youtube search "Maru" if you want to see a really adorable cat
