Social Networking: How do you do it?

Today, I don't want to talk. I want you to talk.

Tell me what forms of social networking you use, which is your current favorite, and which you find the most helpful.

For example:
I use Google+, Facebook, and run this blog. No Twitter for me - not yet, anyway. The rest of my social networking is through non-technological sources (you know, actually going out and meeting people. Scary, huh?)

Right now, I'm loving the huge writers' network I've found on Google+. Other writers post all the time about the things they're going through, and it's usually things I've been through, too. It kicks me in the rear and keeps me writing. Oh, and I keep answering questions for people I don't actually know - Look, I'm smart! Really! (Just don't look too closely...) I've made a couple of new writing acquaintances that way.

Most of my close friends are still on FB, though. We usually organize there. My close-to-home writers' group has a FB page, too, so I can keep up with their lives and meetings. On the whole, I probably get more effective use out of FB. Even if my spellcheck doesn't actually recognize 'Facebook' as a word...

Okay, your turn!
