Oh one more thing... one thing that was very exhausting about this week was seeing a ton of posts dogpile on like "Whaaaat? The json-ld devs / activitypub devs didn't realize X???? What morons" where X is addressed in a bunch of the things above.
In fact we had talked about basically all of these. Criticism is fine, and we might miss things, but don't assume that we're completely incompetent without even trying to engage in a civil way and *find out*. There may be history you don't know.
