Glad you liked them! Despite being childless, the idea of family computing has been on my mind for a while...

Yeah, Facebook is a bad example of a family-safe network. But it has some probably-desirable aspects. A central authority that sets rules and enforces them, one place you can send complaints to. And it has aspects the net's openness too, anyone can make a page. But non-curated mass-broadcasted user content is too much openness for a truly all-ages network.

And I'm inclined to prefer a more decentralised system. One that lets groups of families, churches, schools, etc. to self-govern their networks.
