Ping is Apple's big announcement today. The one that they'll be adding new stuff onto for years and years. The other announcements are just continuations of threads they started long ago. This is a new thread.  

They call it a social network "for music."  

But it won't be "for music" for very long, if it even is just that at startup. 

It'll be Apple's social network for PR. 

It'll be Apple's social network for TV. 

It'll be Apple's social network for developers. 

It'll be Apple's social network for Steve Jobs. 

All of Apple's stores will be on the network, so there will be a location angle. How long before Steve announces a new feature for the stores called (what else) "check in." 

He said it's like Facebook or Twitter but for music, but that's just the opening-day positioning. It won't last. 

Now the big question for the Scripting News community -- is there an API? Will developers get a hook into Ping? Will I be able to ping everyone when I advance a level in Angry Birds? (for example) 

One more thing, great name, but they'll never register it as a trademark. Ping is a big word in this space. Long long before any of Apple's competitors were in the space.
