I was thinking along the lines of being given a list of popular algorithms, but if you find an algorithm you like on another instance you can copy it over to your instance. So it is not necessary to write code and nearly nobody would do it, they would just use ones that other people created.
But I realize this is an extremely difficult request so I’m not really serious when I propose it.
Oh yeah this has little to do with the original question about why bsky is more popular. This suggestion of “let people write their own algorithms” is for the devs who think algorithms are harmful. They aren’t harmful if you give users the power to choose their own algorithm. Techie people can write the algorithms and non-techie people can choose them. Chances are a few algorithms would eventually become the most popular and very few would be written after that, but the point is you let the users decide instead of the Mastodon devs having to write the algorithms.
And now I realize bsky actually has something like this: Custom Feeds. If I understand correctly, they get around the “running untrusted code” issue by not running the code on bsky servers. Instead whoever wrote the custom feed gets the data from bsky, runs the algorithm on a separate server, then returns the custom feed. Pretty clever. https://docs.bsky.app/docs/starter-templates/custom-feeds
