First, I must indicate that I'm new on this stack and may not be aware of how it works here.
I'm referring to this question where all comments seem to have disappeared: Is it possible to run Internet Explorer on OS X El Capitan?
I have looked around this meta and understand that comments are meant to be temporary and deleted once included in the question, answer or no longer relevant.
My concern is that there were some comments on answers that have not been addressed yet :
- A comment on this answer (by someone else) pointing out potential license limitation which is not included in the answer.
- A comment on this answer (by me) pointing out that a part of the answer is not technically correct which was acknowledged but not included in the answer.
- Another comment on the same answer (by someone else) pointing out that the proposed solution doesn't answer the issue.
- Some comments on my own answer (by other people) with some additional information not included in the answer.
I understand it's the choice of the author of an answer to address a comment and edit or not its answer accordingly. But if a comment has not been addressed nor included in the answer, doesn't it constitutes valuable information for future readers, especially when it's highly upvoted?
I have two questions :
- Is this standard practice in this stack to delete comments even if not yet addressed and/or still relevant? In which case, what is the maximum allowed lifespan for a comment?
- Would it be acceptable to rewrite the same comment if the original one has "expired" but was not yet addressed and thus the point still valid?
