I've said it before here, and I'll say it every time it's relevant: Stop using Facebook. Start telling your friends and family to do the same. As the "smart computer person" in many people's lives, you can be the voice they need to hear.
I would like to stop, but the devil is in the details. Facebook is used for many social and business events. I get a lot of work via contacts that come through facebook. Withought it I'm certain I would miss out on some of these. I'd also miss out on keeping up with family abroad. Do you have any suggestions?
It sounds like from your examples you're the perfect case for lock-in they are after. It's penetrated your business and family life so much you're afraid to leave it. That bothered me when I started to feel like that, which is why I left. Since then so many other things have happened (there's a link-fest from another commenter on this thread that I won't bother to compete with - thanks) that I'm pretty good with accepting that I might have missed out on a few things as a result.
