I'm here to talk about technology and it's usage. I'm not here to socialize, I don't know your name, don't care, and haven't even looked at your username. You're just a sentence to me. It's more impersonal than the old newsgroups. How is it social?
it's similar to how you can go to a bar and just say "I'm here to watch the game". You can be asosial in a social community.
