Facebook Alternative for Schools
A parent I know complained to their school that using Facebook for organizing and communicating was a bad idea, since Facebook’s mission is to know everything about everybody everywhere, and she doesn’t really want to help them reach that goal.
The school agreed and switched to Edmodo.
Now, I don’t know if Edmodo is good or bad, but I do very much like the idea of services like this that can replace Facebook for specific uses. They can be better for those specific uses.
