I'm not registered to this website but I thought it seemed like a very cool idea. Something a little different and more interactive then Youtube. I think the fact that there are REAL celebrities interacting with users just doubles the pleasure. Imagine crushing Jessica Alba at a stare off, proving to your friends that you're better then a Hollywood hottie at being creepy. It's seriously worth a browse.
"ibeatyou (IBY) was started by a group of very competitive friends. Whether it was determining who had the funniest celebrity impressions, or remembering how many times someone beat somebody else in Nerf Basketball Contests, we realized there was no real outlet to easily showcase our "skills" with other people, or ways to easily let others decide on the true winner. ibeatyou was created for this sole reason alone. We wanted to create a platform where people could compete with anyone else in the world in anything....Letting the "public" choose the true winner and tracking stats to back up your bragging." - ibeatyou.com
