I only go on a few other sites. Craigslist is one, and surprisingly it is never for pinball machines.
The 501ST Legion, a Star Wars costuming site.
Miniature Market, an online game store, and that goes hand in hand with Boardgamegeek which is everything board game related.
I go online at work when I am bored. If I did not have a desk job with lots of down time I would never be on the internet.
