Ping

Apple’s Ping music social network had a rocky start, it was hit with spam comments,  saw Facebook withdrawing ‘Facebook Connect’ and is plagued with  international availability issues, despite these issues it surpassed the 1 million user milestone in few days after launch.

Apple had introduced Ping as the centerpiece of iTunes 10, users can follow updates from both their friends and their favorite music artists. It includes custom song and album charts, a news feed and 17,000+ concert listings.

A million may seems as a significant landmark, however, it pales in comparison with the more than 160 million people have iTunes, and curiosity is always at a high after an Apple event.
