John Gruber of Darling Fireball, found some interesting information while DNS fishing:
“me.com” is currently a placeholder page hosted by MarkMonitor, a company that specializes in brand-related DNS management. Apple uses MarkMonitor for most of its domains, including “apple.com”, and it’s where they’ve parked domains for future use previously. “mobileme.com” is parked at MarkMonitor, too, but “me.com” is a bit punchier, no?
