What you are describing sounds a bit like a blogroll, which many of us do indeed maintain. Mine is here, by the way: https://susam.net/roll.html

However, Wander is meant to be a bit like StumbleUpon, but without requiring a centralised service that everyone must go through. One limitation of a blogroll is that it does not provide a consistent way to discover recommendations recursively. For example, I might visit your website A, which recommends website B. I might then visit B, but B may not have any recommendations at all.

Every Wander instance, on the other hand, has a defined list of recommendations. It also links to the /wander pages of its neighbouring sites. If you visit the /wander page of website A, the tool can discover its neighbours (B, C, etc.), then the neighbours of those neighbours and so on. It can fetch recommended links from them and present the links within the same console.

Additionally, the tool provides a way to leave the current console and move to a neighbour's console if the visitor wants to continue browsing from there.
