Ping works on local library in iTunes 10.0.1September 26th, 2010
Apple releases iTunes 10.0.1 update with improvements to its music social network Ping. You can now use Ping with your own iTunes library. A Ping button appears next to songs on your library. Clicking on this button will reveal a drop down menu for Ping options such as Lika a song, post to Ping stream and search for artist in iTunes store. Previously, you could only share songs on Ping for songs purchased on iTunes Store.
This release also adds a new Ping sidebar that shows your Ping stream recent activity.
