Hi Filip,
What I knew before they change the name from WebCenter Connect to WebCenter Social is that it was based on a conversation management system called Oracle OnTrack which is a separate Oracle Product, and not made with Oracle ADF, as I'm trying to access Oracle OnTrack document I realized they are trying to tell people "Forget about the Old Oracle OnTrack and focus on the new WebCenter Social, and Social Networking" as I can see from the screenshot(s) in the WebCenter Social page on Oracle.com is that they are using the same old Oracle OnTrack in a new customized interface, still no way to be sure.
