That's exactly the idea. Although, the funny thing about it is: in person, the parents don't really oversee the progress. I imagine it's because I talk conversationally about how the student is doing, his or her strong points, etc. But nobody really tracks how far along the student is progressing with me. That is all done by the report cards (I tutor independently of any tutor center -like Sylvans- and independently of the school systems).

I believe you are correct, however, in that things will shift when it is "anonymous" and online. Kind of like selling childrens' toys: the kids have to like it, but the parents have to be willing to pay as well.
