I kind of like this idea, but then instead of just left and right arrows I want to be able to travel in a multi-dimensional space :)

Links between websites in a sort of hyper-dimensional space! A...hyper-link?

This could be pretty basic browser extension. A little banner at the top or bottom: “websites like this one”

Or website curators all agree on a /webring.txt file (similar to a robots.txt) where they list websites they think are similar?

Or... or.... a little banner that says, "From around the Web:"!
