Yesterday this post was made by Matt Mullenweg regarding the recent accreditation of Automattic as a domain registrar.
I think this leads to a real possibility of dot-wp top level domains (TLD)! As I have recently fallen to the little known affliction of IDA I am quite concerned that this may create a unscratchable itch?! Will this create a digital land-rush for .wp domains?
There is also the potential for a dot-blog TLD that may be more appealing to the Internet in general. As it is, for more general details regarding the creation of a new TLD, head over to ICANN and read this article
