I have seen a number of posts where someone has indicated they have edited it. Things like
- EDIT: Blah-d-bla
- UPDATE: Some new thing just occurred to me...
- EDIT: Lots of new italicized text*
I totally get why people do this; they want to draw attention to the new information or add relevant context to their question or answer. However, like salutations and saying thanks (also understand why people do this even if discouraged) these markers add some noise.
I propose some things, which may be used alone or in combination:
- Discourage the use of edit markers (add a How to Edit box when the user begins an edit (e.g. we have How to Tag and How to Ask already).
- Try to detect the case and notify the user (e.g. if I begin to edit a question and
EDITis one of the first few things I type, it would be nice to have a banner tell me It appears you are trying to indicate you're editing the answer. This is not necessary, we'll highlight the changes when you save.
- Highlight edits with a darker background or side marker (like a change tracking bar). Make this tasteful and undistracting of course.
- Possibly do this while the user is editing so they won't need the reminder.
- Progressively lighten older edits' backgrounds
- Use reasonable periods of time for each edit indication to appear; ultimately it makes no sense to see any indication in the main body of the question or answer that it has been edited—that's what the edited block is for after all.
