Ok i know that we had the last post with bears and gurl gamers, but i found this and i don't know, this might be serious...

"Matt Firor took the stage again to tell us about how ESO will be the most socially connected MMO ever. Facebook, Twitter, Google+… they’ll all be seamlessly integrated into the game from the start. You can import all your friends, circles, followers into the game directly. You can even make a Guild Page on Facebook prior to launch, have your friends join it, have guild members join it, and then import it directly into ESO. Boom, instant guild. Matt claims they ZOS knows that people now have friends everywhere, from every walk of life. They don’t want to make you manage yet another social network. Instead they believe that Elder Scrolls will benefit by making itself as socially connected to the existing networks as possible."

Why?
I dislike the idea, but there are many people out there that post everything at face book and so on. For this kind it will be a nice feature, so long i don't have to be registerd at facebook and so on this is ok.

I'm pretty sure it's optional. I suppose you could belong to a guild that requires it but if you hate social media, why would you join such a guild in the first place?
