Didn't Bluesky solve this problem already by allowing anyone to publish their own algorithms?

I feel like user generated sorting algorithms would be a great fit for RSS. Power users would get an ability to tweak their feeds to their liking, while other users would have a lot to choose from

This is already a problem with things like Mastodon - as soon as you subscribe to some more "spammy" accounts such as news outlets, all the other content is drowned out.

So yes, having kind of re-ranking _algorithm_ can be a good thing, whether we like it or not.
