Togetherville - Social Network for 6-year-olds

For Children, a Social Network With Training Wheels

I didn`t see it posted before.
Anyway, this is supposedly for kids under 10.

Togetherville allows parents to build a social circle for their children based on their own collection of Facebook friends. The children can then interact with the children of their parents' friends, and specific adults that their parents have chosen, in a semi-private environment. The content on the site is curated, so children can play games, make art projects and watch or share videos, but everything they have access to has been vetted in advance, Mr. Dhillon said. Children can comment on their friends' posts directly through drop-down menus of preselected phrases. If a user wants to say something that is not on the list, he can submit a request that it be added.
