@******* since you are capturing the social comments in a separate database, cant you inject that information into xenforo tables and include the posts made by the social addon into the pages timeline and make it look like normal posts? I believe that is the killer feature that everyone is looking for.
Right now all the social posts appear directly under where you position the addon and doesnt really follow the discussion since all social comments are placed together and hidden under the google+, and facebook etc tabs.
