I am mid twenties, and was homeschooled my entire childhood. My father owned a technology company, and brought me to work with him most days. People talk about homeschooling being damaging due to the lack of exposure to the "real world", but I have had more exposure to reality than most, due to the constant exposure to actual working life.
Don't be afraid of "sheltering" your children by not having them be part of the system. There is so much more out there than the system. Your kids will turn out weird vs other kids raised in the standard environment, but its a good kind of weird.
My family was very involved with the homeschooling movement in our state, so I am more exposed than most to the sub-culture. Feel free to ask me any more specific questions.
