I'm writing some ActivityPub stuff, and wanted to make sure to get RSS in, done right, etc. However i never use RSS so i have little insight to good/bad/irrelevant RSS impls. Any wants or must-haves to an RSS implementation over a Fediverse instance? My rough plan is to just include RSS in any places i expose JSON endpoints for data. Though i'm a bit undecided if there's any value in user activity stuff, like comments on an article, etc.
