Then, when posting, you can post to "Family" instead of "Followers" or "Public", and have the message addressed to them only.
It's almost the same as adding all of them manually to the "To" list when posting, but a lot faster.
And yes, they are public, and, AFAIK, can't be private ATM.

Thanks for answers. It thought they might be something like that. Good to know. Maybe I will find use for them someday.
