I am very much in support of offering alternative options to centralized black-box apps with dubious profitability mechanisms. An option that doesn't catch on to the tune of a billion+ users is better than an option that never existed. The success of technology scaling to a global amount of users should be weighted also with possible-to-measurable harm. Is there activity in the space of developing open-source social media algorithms? It has been interesting to see Threads and bluesky build integrations with Activity Pub (though there is risk for the embrace-extend-extinguish playbook to be applied against it). Are there similar possibilities for generating algorithmic standards for social media feeds that can be understood as deeply as one wishes to?
