One particular problem is that when you point out a mistake in someone's answer, you have to check several times until he fixed it so you can delete your initial comment.

Otherwise your comment will likely be flagged as obsolete.

To avoid this issue, I was thinking about an option available when you post a comment, that would make the comment automatically auto-delete after one of four cases:

  • the poster edits is answer,

  • the poster acknowledge (with a little check box) your comment,

  • the poster respond to you,

  • a certain amount of time passes.

What do you think about such auto-deleting comments? What would be the downsides of this system?

    $\begingroup$ Obsolete -flags we can handle quite quickly. In most cases it is relatively fast to ascertain that the comment has, indeed, served its purpose. Thanks for asking, but this is really a non-problem from the point of view of mods. Of course, we probably have very many obsolete comments in threads nobody has bothered to visit for a year or more. This feature-request could help stop that problem from becoming worse. Provided all the commenters familiarized themselves with this feature (after it got implemented). Upvoting the good intention. $\endgroup$ Feb 5, 2017 at 9:47

    $\begingroup$ This seems related: Can we have temporary comments that can be read and deleted? $\endgroup$ Feb 5, 2017 at 9:47
