Incremental_anarchist [he/him, he/him]

Hmm, interesting they use the term echo chambers here. Everything here sounds good, but they continue the demonization of “echo chambers”, which personally I find unwarranted. The issue is the spread of hateful content and misinformation, which they do appear to be addressing. Personally I’d like to get rid of algorithmic feeds altogether, for that purpose. But filter bubbles / echo chambers are not inextricably linked to spreading hateful content and misinformation though. A marginalized individual not wanting to interact with those who actively wish them harm shouldn’t be forced to. And hell, I might even be okay with focusing just on misinformation. An explicit threat towards -phobes is always justified imo.

Discourse is the de facto standard for what you’re asking for, and has a LOT of customization and plugins community.
