If I see someone type "loose" one more time I am going to LOSE it, just completely snap. I know this is the web, and I kn0w ppl tipe liek th1s, zomg!!!1!1!! but for some reason "loose" really gets on my nerves more than anything else. I don't know why, but every time I see it I feel a little part of me die. The worst is when I see people with totally great spelling and grammar use it. I'm starting to think people actually believe that's the correct spelling.
So, what about everyone else? What are your pet peeves on the forums/web?
