My YOShINon RSS reader incorporates about 110 feeds, and, unlike the majority of RSS readers, actually treats RSS feed items as items that are stored in a database so it can present those items in various ways. Most news sources ranging from The Guardian and The Bulwark and Jacobin as well as phys.org and MDPI publishing still have RSS feeds.
It has screens to view things based on database queries, full text, and embedding similarities but the main UI looks like TikTok or Tinder for text, showing me articles it thinks I will like mixed with random articles to keep it calibrated. It spins like a top. I also have another thing called "Fraxinus" which was a cut-and-paste job from it that works as a bookmark manager and image sorter, the plan eventually is to mash them back together.
