Not my medium, either. I do not do much on Facebook. I am on LinkedIn, but only for the local groups. I dropped all the national/international chats right away. I goto sites like this one, targeted and focused. My Favorites bar includes SlashDot and Ars Technica.

Interesting. I have never felt obligated to answer the phone just 'cause it rings and I don't think I'll ever tweet either, but it was interesting.
