From TechCrunch
The wow.com
domain name has laid dormant since at least 1998, when it was acquired by AOL along with other assets of Compuserve. The domain has been coveted by a number of AOL business units over the years, though. At one point there was a discussion of it being used to house the netscape social news assets (they eventually settled on propeller.com).
If our source is correct, a decision has been made as to the long term use of wow.com. It has been transferred to the AOL Games group
and is currently being turned into a - you guessed it - World of Warcraft social network.
