Heck, that probably describes my sister as well. She would mock me for being a computer geek -- I was the one with the 24x7 netconnected linuxbox in the house in 94. And yet often her social evenings would revolve around her and a friend or three gathered at the family PC, AIM'ng all of the friends who weren't there. Yes, she was social (did you know there was a 100 user buddylist limitation, or used to be) and I was not. Yes, I wrote communication programs and she consumed them. But Sterling is right... the general promiscuity of all our cool toys indicates social contagion.
She (vermonster) has had a livejournal account for months.
