Homeschooling seems to be regaining its popularity nowadays. Can anyone tell me what's with it that makes it worth while? What are the pros and cons?

I used to tutor children who were semi-homeschooled by me and semi-homeschooled by their mother. Honestly, I think if you're able to develop an appropriate curriculum that's on par (or even better) with schools and their grade, then educationally speaking, there's no difference. However, socially, you can imagine the detriments of homeschooling. In kids that aren;t the most sociable, homeschooling will only exacerbate their lack of social skills.
