I think this “marketplace of algorithms” idea (aka algorithmic choice) is a bit naive. Imagine using an app for the first time. What algorithm do you choose? Now remove your technical context and imagine reading through the top 10 algorithms to make a choice of which one to select. Twitter actually has quite a few knobs for curation (eg you can apply Regexps to filter content), and Id be very interested in knowing how many users actually use those features. Id guess its a rounding error.

I envision it not as a configurable app, but instead each approach to algorithmic feeds is a separate app/website. All the apps have all the underlying fediverse/activitypub data available for them to serve up, but each has a different approach to curating content. Users would just choose the type of experience they want by choosing different apps/websites.

Its very easy, you have a configuration setting with the list of algorithms and a short textual description. Users try them and quickly change off ones they don't like till they settle on one they like best.
