jesus, i made a lot of typos in that post, and i can't edit because this is Nostr, not Mastodon.
i sort of want to write up a NIP for an edit feature.
it took years before they introduced edits on Mastodon and it was highly controversial, and the solution that Mastodon finally landed on was to allow it, but also to include an edit history you can view for every post, plus notifications to anyone who had reposted it.
it helps that Mastodon also has undo for every action, so if somebody edits their post, you can undo it.
tbh though, people generally just edit to correct mistakes, not to pull some bait and switch shit on you.
