Here is a decent blog on how to “safely” allow children on to Facebook:

The key things for me though, are “who has time?” and “how can we track this consistently?” or how about: “Who knows how much time is good or bad?”
Sure there are guidelines as pointed out in this article, but there needs to be a better way.
Why can’t we use the technology that is causing these problems to assist in solving them?
