Each link is completely annotated with a fat paragraph describing the site and its potential benefits to you and/or your kids. It's kind of like a mini-review, so you can tell before you visit if you'll like it or not.

Anytime you can get a 'Net filter like this sent directly to your e-mail inbox, I recommend signing up and testing it to see if you like it. You can't lose. And it's free, so go sign up immediately.
