Apple Thoughts: Share Your Playlist With Ping

"Ping just got a micron less useless on Friday with the addition of new functionality: the ability to make social playlists and share them with friends."

I still haven't done much with Ping, and to be honest I probably won't until it has Facebook integration. That is where most of my friends are so it is pretty worthless to me without the ability to share on Facebook. I like this feature however. How about you, anyone finding Ping useful?
