Following today's Ping Twitter integration, many on Twitter started blasting the overly long Ping URLs. Now, MacRumors points out that one of their readers speculates that Apple could use its own iTun.es link shortener to help fit Ping links into Twitter's character limitation.
The www.itun.es web domain currently forwards to Apple.com. MacRumors did some digging and found out that Apple has been the owner of itun.es since December 2006 when it was registered by MarkMonitor, the brand management firm Apple uses to register all of its domains. MacRumors notes that since Apple has owned the domain for almost four years it is unlikly they bought it specifically for a link shortener purpose, but with today's Ping Twitter integration it would allow the company to put the domain to good use.
