Tried it. Didn't work for my children. As the article says though, it's not for everyone. My kids are super-smart, but lazy, and unfortunately need structure. I homeschooled them for several years, but both of them asked to go to "real" school eventually, one by the age of 6 and the other by 8 (they were about 2 years ahead of the other kids when they enrolled). I think that it's worth the experiment though, but be prepared for the unexpected as you're dealing with an individual, not an ideal.
