Well, since I had to pick one, I said "Entertainment". But really, I visit entertainment sites, forums (obviously), search engines, and whatever I Stumble Upon really!
Fell in love with his Keno waitress,
They honeymooned in Memphis,
They were married by the drive up window.
Trailer parks, neon signs,
And an empty box of Lucky Strikes,
All used up on the dashboard of America.

Wow, the forums option is wicked popular... that's just about ALL that I do. I do games occasionally, but forums dominate my time. I used to play backgammon, checkers, and golf at nabiscoworld.com, and pool and a few other games at candystand.com, but the forums are dominating my time.
