The world's reaction is also negative. They don't want to wear a box strapped to their face to interact with their friends. Seriously, look at the reaction on Twitter by non-gamers and Facebook users. It's being met with incredulity and mockery.
They don't want now, but wait 'till Facebook does "their magic" on them :) That "networking effect" stuff is not buzz-speak, and they know how to wield it.
Plus, gaming and socialization go hand in hand - it's amazing that others just don't fucking get this yet and see "gamers communities" as just niches or islands.
