As I expected, I have still not received an invitation to join Wirehog. Nor do I know anyone who has. Even more alarming is the disappearance of the Wirehog website. Were this another company, I would conclude that Wirehog was simply vaporware.
Despite such issues, i2hub seems worried about Wirehog's impact, going as far as registering wirehog.org and wirehog.net. The date on the two registrations is August 13, 2004 - the same day that the Crimson announced Wirehog's creation to the public.
