My net browsing is fairly limited in that I tend to visit the same sites time after time.
In order of most used it would read something like this

Partypoker.com
Yahoo games (POOL)
Cannabis.com
Digitalspy.com
Bizarremag.com I like wierd and wonderful things and you don't get much wierder than Bizarremag .
I also like almost anything to do with motorsport too so I visit a few of them like F1 ,Motocross and rallying sites.
