In no particular order-
Airliners.net- for obvious reasons
Cracked.com- I never remembered the magazine being this good. I once won a contest and had a North Korea related graphic published, so they like me and that always helps.
.com- news website for my home state of Alabama. The comments sections are the best. I love to read how the most benign of stories can be twisted into being the fault of Obama, liberals and/or Lincoln and his Northern Aggression.
Facebook- not so much now that I've moved back to the states.
.com- Support website for those like me who've had weight loss surgery. I read it mostly for the forums, where formerly fat middle aged women bicker with each other about who's the prettiest, who had the best best surgery and why someone's going to die because they ate a cracker. The wars here are VICIOUS and have had lawyers involved; they make anything on 4chan look like a Montessori chat room.
Nature forms us for ourselves, not for others; to be, not to seem.
