There are a number of tools. Again, we could compare lists and help get a list for you. As important as that is, what different studies have repeatedly shown was the failure of parents to use them, or to know how to use them, or to get access to them, and the limits of what we can get individual parents to do, because there's been a pretty hard push towards that. There are lists, and we can talk about those. There are issues with the fact that the older and more sophisticated your children get, the better they can quickly learn how to get around those, so there are limits to them as well. They exist, but also, I want to remind you, because you've heard this testimony quite a bit, that they put the burden back on individual parents as opposed to a collective leadership.
I think there's room for both. I believe firmly in education of children and parents, but I believe that we need to do something about making their job easier.
