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.
