Thanks for the idea! LinkLonk already has a concept of a "list of links" - collections. When you upvote a link you put it into one (or more) of your collections.

What you are suggesting is similar to another idea I had (https://linklonk.com/item/9146000221282140160): "An option to generate a publicly visible url for any of your collections. This could help you share your collection of liked items with other people. And it could help LinkLonk get new users."

Adding an RSS feed for these publicly accessible collections would be a natural extension.
