That's a very clever site, but I worry about scalability- If you're adding links manually you're going to run into the same problem that yahoo ran into, but without the Ad-revenue to try to overcome it.

I'm also slightly worried that it's a difficult thing for kids to type or say, but I imagine they'll have it bookmarked for the most part.

Not bad at all, how do you guys compile the white list?

Very good clouding.
