Jesus Christ you people, get your head of your collective asses. Gabe isn't saying that he'll force Facebook and IM and Twiiter down your throat while you play single-player. Read the story again, and this time, carefully. He is merely using Facebook as a point by saying that most people nowadays are integrated into these social sites. That's a fucking given. People like social integration, and Valve wants to find ways to bring to the table but still deliver single-player experiences. How the hell did anybody here get that Facebook was going to shoved in your face while you play Valve games? Nowhere does he say this. Nowhere.
When did this community turn into a bunch of whiny, jump-the-gun babies who don't read the stories they whine about?
