Looks like only avast! WebRep and WOT have joined the social (without Facebook or Twitter app) scene. It’s weird; although Norton has something for Facebook, you have to install it as a Facebook APP, while with WOT and WebRep, it’s in the browser (no need to approve an application on Facebook or wherever). Also note that WOT and WebRep are the only 2 mainly-community-reliant services.
