What do you think of the word Blimple ?

There is a story behind Facebook though, and it certainly wasn't original to them. Like you say though, strangely enough they managed to get it registered at the time.

In the last 5-6 years though the .com thing has sort of gone though. Most of the good domains have been taken and people are buying domains that are actually pretty poor and parking them. It's unfortunate because i don't think there will be any more big name websites around with a .com domain name that has been registered in the last 3 years.
