@aidalgol @kaniini @lain Urgh, no I don't know of a good writeup, but here's the tl;wh (too long; wasn't here):

- StatusNet written and the base of most of GNU Social (and generally written and had a community that was very lefty, but occasionally left-libertarian) but StatusNet closes shop. GNU Social is the continuation.
- "chan culture", originally jokingly problematic (arguably joking doesn't make it less racist or sexist), becomes "ha ha only completely serious"
