Twitter has just upgraded their services to include iTunes App Store integration. Now you no longer have to go into iTunes or the online iTunes App Store just to find out more about an app – the Twitter site now lists the important app information at the bottom of a tweet that an app is linked in. Pretty nifty integration if you ask me. It’s nice to see Twitter evolving from a simple text-only micro-blogging/communication service into the huge social multi-media network it is now. The feature only works on the official Twitter website at the moment, though you can expect it to roll out to the official and third party apps in the near future. Any guesses to when Twitter will support the Mac App Store, Android Market or Windows Marketplace?
