I totally can’t remember why, a few months ago, I looked again, but their network map captured my imagination. It’s kind of hard to describe; many of the places on it are gone, and many that still exist don’t really need to. Still, a little poking around may not be entirely unrewarding.
While writing this, I made the mistake of visiting Wikipedia and found a perfectly ordinary entry giving the who/what/where/when of jodi.org. I preferred it when I didn’t know any of those things.
