Programmer and researcher in compiler construction, formal methods, constructive mathematics, type theory, category theory, and intuitionistic logic. I am also passionate about software freedom, functional programming, deterministic software, type safety, and enthusiastically opposing framework-driven programming.
It may be preferable for visual organization if hub.sr.ht, git.sr.ht, and hg.sr.ht had an option to pin up-to 3 repositories. Preference above all would be hub.sr.ht for projects with many repositories, where one specific git/hg source is considered the "main project".
Visual demarcation could be moving the repository to the top of the list, darkening the border around the listing, and adding a svg or unicode pin symbol.
Some RSS-style feeds such as https://export.arxiv.org/rss/math.CT requires special RDF parsing.
This is currently being worked on in the following branch. https://git.sr.ht/~brettgilio/org-webring/tree/feature/reuse-nnrss-parts
Essentially it will be a mockup similar to what I did in this post https://brettgilio.com/posts/2020-08-16-what-is-a-contributor.html. However, we can and should apply this to the entire webring, not just sharing a reply. A pinned post could have a push-pin icon next to the title to designate it as a pinned post (first in the order), where the rest of the most recent posts will be appended to the right of that pinned post. Does that make sense?
As far as implementation, some information would have to be specified, and I think a post URL would probably be the best choice, and we could do matching from there.
