I know many people are server admins for large companies that may be interested in this. The .CO TLD has been opened up for pre-registration for non-Columbians.
Godaddy and other registrars are trying to convince people this is the next big TLD – associating .CO with COmpany or COrporation or COmmerce. The sad thing is, with all of the marketing about to take place, it may just work.
Trademark holders, and current third level .co holders have first dibs, then people willing to pay $299, and finally people only willing to pay $29.
So, like .info, .mobi, etc, if your company has a presence worth protecting, you may need to shell out the $$ to protect against squatters.
Here’s a link to Godaddy’s page about .CO:
It also happens to be the 25th anniversary of .COM today.
