You're touching on something I've thought the world needed for a long time: a Wikipedia-like wiki site with world-curated comprehensive descriptions of the affordances of various social SaaS platforms. Ideally with a classification scheme and class-specific rubric.
While all those affordances are important, the ones I really want an authoritative, well organized reference to look things up in are moderation and social-management related. Pre-moderation? Post-moderation? Separation of read, write, and moderation permissions? Individual vs criteria based? Scheduled? Moderation authority by appointment or election or distribution? Shadowbanning? Disemvowelment? User affordances like blocking and muting? Notifications? Tracking/following? Etc.
