Am I allowed to mention adult sites in here? Haha
Seriously though, so many people use the internet for porn there's kinda no point denying it
Anyway, apart from all that I guess I'd say Facebook so I can stay in touch with my friends. I started using Twitter about a month ago, some REALLY strange people on there. I got an invite to join here and I'm loving it, it's been good to get my writing and typing practice before I launch my blog (just working on the design atm).
What else... EBay! I shop A LOT. I like a various clothing and fashion sites. Actually I follow loads of fashion blogs, just don't always have the time to catch up all the updates...
