Questions and answers are often edited following a query in a comment to expand or clarify something. This is clearly a good thing. What I want to discuss here is that sometimes this is edited prefixed with "Edited to explain..." or "Edited following the comment from...". For example, this answer.
To someone reading the post for the first time, this seems an unnecessary extra complication. Personally, when I edit I write so that a new reader will be able to read the post seamlessly - if they want to see the edit history that is available separately.
Which approach should we recommend?
Should we impose this decision or let people make different individual decisions?
