I haven't; I _did_ read Unschooling and Why Johnny Can't Read by
John Holt, as well as Summerhill by J.S. Neill when I was 14
years old and in the 8th grade.
Then, at 18 yrs old in 1990 college on the newly minted (to me)
Internet, I found a group of people who ran Sudbury schools
around the world and chatted with them a lot in mailing lists.
So, I have always had an interest in alternative schooling; I
have loved the rise of homeschooling with the Internet over the
past few years with some excellent (and some not-so-excellent)
online schools for elementary, middle, high school is a
marvelous development, along with the self-education (for better
and for worse) available via the Internet in general.
So it's a deep interest across all subjects including history. I
do most of my learning via the Internet; I've done so for the
past 27 years now; so it's not TOO often that I'll crack open a
book to read cover-to-cover, but I like going to the library and
flipping through, looking at headers, chapter titles, pictures,
index, table of contents, italicized - in short, speed-reading
through it... in an attempt to increase the amount of different
perspectives as I can.
