Can Someone Explain Facebook/Twitter?

[Trek420]

I now feel like I know my brother much better than I have done in the past 15 years when we were on separate continents and spoke only briefly at Christmas when we both go home.

Is this the same brother to whom once you asked what's been going on lately and he said "check my Facebook page"?

What works for me; Facebook, people I know IRL but distance or time constraints don't see as often as I'd like. Great to keep in touch, post a picture from wherever I am, have gotten in touch with old school chums and I mean like elementary school and two ex's I get along with

Discussion groups. Most there don't have my real name, some I never meet. Groups like TE we have stuff in common and of course I have family on TE but the groups are strangers mostly with a focus on one issue (unless we're drifting)

I'm twitter impaired don't use it at all.
