Apple integrates Ping with Twitter, not Facebook
Apple has made Ping, its fledgling social network for iTunes Store music activity, a little more social by integrating Twitter. You can easily add new Twitter friends to your Ping account, and share Ping activity like purchases and comments back to your Twitter account. Facebook integration, which disappeared early after Ping's launch, has yet to reappear.
