Perhaps a site could kick off where people proposed sites for Web Rings, edited them. The sites in question could somehow adopt them — perhaps by directly pulling from the Web Ring site.
And while we're at it, no reason for the Web "Ring" not to occasionally branch, bifurcate, and even rejoin threads from time to time. It need not be a simple linked list who's tail points back to it's head.
Happy to mock something up if someone smarter than me can fill in the details.
Pick a topic: Risograph printers? 6502 Assembly? What are some sites that would be in the loop? Would a 6502 Assembly ring have "orthogonal branches" to the KIM-1 computer (ring)? How about a "roulette" button that jumps you to somewhere at random in the ring? (So not linear.) Is it a tree or a ring? If a tree, can you traverse in reverse?
