I'm glad to see this. As I asked way back when, Apple is now finally starting to leverage social media. This is a big deal, and one that Apple will wonder why they took so long embracing. See, Apple is on one hand afraid of a message it can't control (social media) yet on the other hand benefits more than any other company from the fervor of its fans (social media).
Would you follow an official Apple Twitter profile? And what would Apple say in their updates beyond product news? Stay tuned!
