I love being labelled as a mere "Sony fan". Always brings a chuckle. Although, based on this thread, it's good to see who stalks who.

In any case, my profile is blocked to people who aren't friends because I prefer not to be bugged by the spam bots. In regards to the "Xbox fans", I believe BMaker said it best. 

For me, won't matter after Dec 31, 2013, however. ;) 

why what happens january 1st?
