This question sprang to mind due to this question on the main site. My original comment about the question not fitting is no longer applicable since the OP rephrased the question. In fact all the comments basically are no longer useful.
In instances like this,
- Should we as community members delete our comments?
- Should the moderator re-opening delete/tidy the comments?
- Leave them as they are as they pertain to previous form of the question?
- Should they be marked in some way to show they are about an older version of the question?
