@ossobuco,
Problem for me is that I don't do facebook. I should, I should.
Seems too complicated to me, to keep my familial/long time friends in some kind of separate room, me always using real name.
And a2kers, also real name, most of them already knowing mine.
I'm not sure I'm bright enough, how to deal with it, re friending and all that, but not making talk a mixed up mess.
This is complicated in that some of my long timers - pre a2k, might like a2kers.
Or, the opposite.
