After CEO Tim Cook admitting that music-based social network Ping had been one of Apple's occasional missteps, saying "I think the customer voted" on it and that Apple doesn't need its own social network, Apple has begun notifying users that Ping will no longer be available as of September 30 and is not accepting any new members. The two-year-old service, built into iTunes, gained millions of accounts when first introduced, but had issues with a failed plan to incorporate Facebook likes and sharing and faltered shortly afterwards.
