I've been living across an ocean from my family for over 10 years, deactivated my FB account 2 years ago and never turned back. So I really don't understand your "ridiculous to even consider" -- there are many other ways to keep in touch, and doing without the firehose of low-quality information (wall posts, movie recommendations, etc.) pouring through FB gives you more time to focus on the high-quality information that can be better communicated through other media (phone, email, etc.)
I understand that leaving FB (or never using it) is not for everybody, but "ridiculous to even consider" goes way too far. I think actually it would be great for a lot more people to consider it, even if they end up deciding not to actually do it.
