I personally can't stand Twitter and only had an account to market Hive, then stopped using that when the rednecks took over. The algorithm I am exposed to most is meta because of running a marketing company with social media practice. We study it constantly for developments and opportunities for our clients but it is always a guessing game at what goes on behind the curtain with corporate platforms.
A neat one to watch will be tic toc as the North American ownership has slid to another billionaire controlling social media. I have already heard reports of previously popular content creators having their content plummet in reach because they might have an opinion different than the agenda/portfolio of the new overlords.
I sometimes wonder what benefit an algorithm would be on Hive. The Trending and Hot sections are almost useless to me and I have to hand crank My Friends almost blindly searching for content and community members I want to support. It is called networking I guess. Couldn't imagine having someone I follow disappear from my feed because they had a change in habits or schedule. Glad for that.
Rage against the algorythm!
