It’s the hidden algorithms that I hope don’t catch on, because that puts someone else in charge of what is seen and is just a continuation of the same issues with Twitter and other closed platforms. But I’m not against the idea of algorithms that help with content/people discovery. Ideally they should be user definable and open/transparent as to how they’re working, even shareable. The idea of an open marketplace for algorithms has been tossed around and I think that could be interesting. So long as users are left in control of their own feed and can turn them off.
