[Bluesky users can pick their own moderation systems and recommendation algorithms] How exactly am I supposed to get enough information to make this choice?
First off, I'd love to pick the algorithm "show only stuff from my friends, in chronological order". I'd hope they'd offer a simplistic no-brainer like this, and it'd be easy to understand.
Second, I'd rely on journalists or academic researchers to study the moderation+recommendation algorithms and I'd go via trusted sources. I'd wait until a review article comes up in Ars Technica and pick there. I think non-technical users would only pick if the question becomes significant enough to filter through to general society discussion. Maybe there'll be some viral videos of TikTok from "influencers" who noticed that they preferred one or another algorithm, and it'll spread through that and word of mouth amongst friends?
Do you have any friends who say "I used to follow instagram but there were too many political articles and I switched to TikTok because it's more fun"? They were switching partly because they discerned a difference in the recommendation algorithm. (which is more or less the secret sauce of TikTok's success).
Third, I wonder why you think end-users are fine at picking up differences between the algorithms used for internet-search (google, bing, altavista), and for map-routing (waze, google maps, apple maps)? How are they basing their choices? Why won't the same kind of end-user choice about subtle and complicated algorithms also apply to feeds?
