I'd always heard about the Flat Earth Society, but never really in very much detail. Then I found this 24 year old interview with its founder, which provides a very nice summary. Also gives an insight into what it's like to talk to a person who's nominatively sane yet completely off their rocker. Has some interesting post-scripts at the very end.

To see if the FES was still around after its founder's demise, I did a google search on the name. I ended up with a bunch of sites claiming to be the FES, but on examination I'm of the opinion they're all hoaxes. It would seem either the FES died with Mr. Schadewald, or his successors have yet to "discover" the Internet.
