It's important to note though that the type of things that this 'plug-in' does is social already. When you're logging in to Pepsi SoundOff you already know you may want to share something on your Facebook feed, or you don't care about what brands can see your information on Facebook. Each service should consider what their target audience is and work towards using that method.

To be completely fair though, I never let anything login with my Facebook account, I just don't want other sites to have access to that data. And I would probably never use something like what this place provides, so people who use the net like me would never show up in their numbers.

In what way? It doesn't offer anything at all to counter that post, and doesn't in any way support the notion that users like social logins. It just shows that users who used social logins spent more time on the site.
