Agreed. A lot of companies are worried about the .biz extension. Don't know if it will be threat, but not sure if it is.
.biz puzzles a lot of companies. It means 'business' which all companies are in, thus it is right that they fight for their little plot of bizland.
.biz is not available for direct speculation, since offering it for sale is sufficient grounds enough for Neulevel to terminate the domain. 7,500+ .biz domains were just deleted at the snap of a finger.
