Tim Cook hit it right on the head last night in his comments on Ping.
We tried Ping, and the customer voted. (link)
Ping was meant to be Spotify but it was stuck to downloads and actionable-click sharing. Conversely, Spotify streams and shares music playlists seamlessly.
Apple should let Ping fade even if iTunes all of a sudden becomes part of Facebook's frictionless sharing timeline and adopts the all access streaming model.
Apple simply doesn't build social networks but it optimizes its operating system for easy social interaction. Cook hinted at a greater Facebook partnership in the iOS.
Facebook has hundreds of millions of customers. So, anyone that has an iPhone or iPad, we want them to have the best experience with Facebook on those platforms. (link)
Deeper Facebook integration into the iOS puts pressure on Facebook to differentiate its phone.
Besides Facebook, Cook didn't give anything new away in his interview except the improved version of Siri. Undoubtedly, Siri will make it easier for customers to engage in social.
