@julian This was ~4 years ago but I asked someone on the team (I forget who) if it would be a welcome PR and I was told that it probably wouldn't be, so I didn't make the PR.

Of course that was a long time ago! Also of note, this was completely and totally a hack and I don't think my actual implementation is what I would want to put upstream at this point. What's more interesting is that it hasn't been the cause of any UI concerns; basically what you postulate above, that the "hide long content behind a cut" functionality pretty much solves the problem, is true.

@julian said in `Update(Note)` quirk:

This whole thing could actually be sidestepped if we sent timestamps with our activities, but that's not in the spec, so I guess nobody does it heh.

Not sure what you mean here? Any Mastodon (or misskey or...) Create(Note) has a published property on the Create activity with a timestamp and a published property on the Note object with a timestamp.

Just coming across this now, hello everyone -- I wanted to say that Hometown has implemented what @julian proposes in the OP for its entire existence, since about 2019. It's worked quite well!

To be fair I have this cool software I'm working on that helps me answer that question immediately
