When iTunes Ping originally debuted in September 2010, for the first few hours Ping let you connect your Facebook account with your Ping account, making it easy for you to find your Facebook friends who are also using Ping. Unfortunately, that’s as far as the integration went, there was no ability to share things with your Facebook friends.
Several weeks ago, iTunes Ping introduced Twitter support, allowing you to connect your Twitter account, see who else you’re following is on Ping, but also goes one step further by allowing you to tweet your recent activity on Ping (Liked items, as well as other posts you make).
Thanks to this integration, it’s possible to pull this data back into Facebook, sharing your Ping likes and posts with your Facebook friends. Sure, it’s hacky, and completely messy, but it works, and is better than nothing until Apple and Facebook kiss and make up.
