May be one of multiple abandoned features
The latest revision of terms for the iTunes Store may point to a missing feature, observers remark. "We have changed the iTunes Store Terms and Conditions to provide you notice that if you have opted in to the Ping social network and use the new Ping Sidebar," the text reads, "iTunes will send information to Apple about the content you select in your iTunes library in order to provide you with Ping personal recommendations." There is no identifiable sidebar for Ping, whether in iTunes 10 or iOS.
Apple could conceivably be referring to the Ping menu item on the left-hand side of iTunes 10, but it lacks any similarity to the Genius sidebar. A Ping sidebar could therefore be forthcoming, or something Apple abandoned before making the social network public. The company was forced to abandon Facebook integration after it failed to get consent.
