I follow a similar strategy; but for me, 98% of Facebook usage is keeping in touch with people I've known for years, but are geographically distant. They know my nickname, they know how to find me, and FB does in fact help us keep abreast of each others' lives pretty well. (Photos, life events, amusing anecdotes...) On the very rare occasion I add someone new to Facebook (1/month max) it is not difficult to say "I'm on Facebook as Nickname. My work e-mail address is not connected, use specialized-address." It requires about a minute's out-of-band explanation, but so what? I have no interest in being friended by random strangers.
