I ended up here because it was in the related links of a new question. The original version made be pull a face, so I've adjusted it. However, given it has been accepted and unedited for about 7 months, is this appropriate?
I'm inclined to say the answer is yes, as long as it improves the site, but I would like some wider community confirmation please. Are there any cases where it is instead right to leave old posts alone, even if they can be improved?
Notice that someone has posted a new comment on the question because I've bumped it with my edit, for example. So are there any other potential issues here?
I'm not, I should say, intending to go trawling for old posts to fix...
