When I heard about .co I immediately groaned and said "not a faux .com domain". Yes, I was skeptical.
But I've had time to rethink that thought. When I started looking into .co and how they have positioned themselves in the marketplace I changed my mind.
.co sees itself as an opportunity to get the name you really want (and have cleverly set their landing page to www.opportunity.co ). They use the example of The Madison Group who had tmgstudio.net and have now been able to rebrand with tmg.co.
I am a bit of a pedant about the original gTLD extensions. In my books .org is for organizations, .net is for ISPs, and .com is for companies.
.co goes one further than .com - it is right for commercial purposes of course, but then extends to communities and contests - it's a very clever repurposing of this domain extension. They also suggest communication and content - really the web is their oyster.
With only 400,000 (plus change) .co names registered, there is an amazing opportunity for all you .biz, .net, and .info branded websites to get a well targeted .co name.
Shorter, stronger, better!
There are so many great names still available - here's a handful:
