Yeah, the worse we ever did was to implement editing and deletions. I now realise twtxt should follow a “written in stone” approach. Having been a strong proponent at a time for edits/deletion, I wholeheartedly regret it.
@david I don't want to start the discussion again, but edits wouldn't be an issue if we had agreed on a better addressing scheme. Maybe edit more as a quiet riot. :-P
