Landrush for .co  has started and will extend from June 21 through July 13. All trademark restrictions have been removed, allowing anyone to apply for available .co names. Duplicate applications will be decided by auction.

Single character .co domain names have been getting significant attention.  Twitter acquired t.co and will be developing this as their proprietary domain name shortener.  Ten bidders initially participated in the auction for e.co which was ultimately sold for $81,000. 
 
There are still opportunities to apply for prime keyword domain names to create memorable URLs for   micro-sites and advertising opportunity.
