>>I use it — mostly lurking, rarely posting/liking — mostly to keep up with family/friends and a couple of interest groups (Free Republic being one).
That sums up my use as well.<<

Here as well. My family has a private FB page where I post (on rare occasion). Nothing in public, not even likes.

If you happen to have a private email domain for your family (e.g. family.org or something similar) you can use a product called Yammer. It is owned by Microsoft now but is essentially Facebook for corporations. It allows only users who have email addresses that match a company domain to gain access while restricting all others.

So dad@family.org, mom@family.org, etc. can all join and exchange social media posts/pictures, but if you don’t have an email on the approved domain, you can’t join at all.
