This webring isn't so much a ring as a wire, as one of the websites doesn't have the footer. This was always the problem with webrings in the first place - one broken link in the chain ruins it for everyone.
Just like token ring based LANs

I do think webrings are badly needed again, though, to serve the same purpose they were developed for in the first place: discoverability.
It's become very difficult to find the good (according to my tastes) websites these days.
You'd probably want to measure click though rate and do manual review. Could also have a redirecting page so that the back button allows the visitor to flag or report something.
Having sites just list others the site owners think are similar is just the site providing a list of links to "friend sites" -- which also used to be a common thing. That's also fun and useful, but not what webrings are about.
"Other cool sites" lists were quite popular back then. That's what I used for site discovery instead of webrings.
As a way of discovering content, I love the idea.
Let's see ...
I sprung from rung to rung
Skipping past the dung
On my wall let it be hung
That my feats remain unsung
