Quite often we see posts that were put on hold for various reasons without any comment on the question.
Canned close reasons are mostly self-explaining (or at least they should be) but I sometimes feel that an individual user who took time to contribute here with writing a question should deserve some individual treatment.
In addition new users may not be aware of many aspects of our quality requirements. For them it would be vital to learn what is wrong with their post to avoid closing, which could lead to a question ban.
Therefore I would like to hear what our policy should be. Should moderators write a comment after a closure (we get an auto-flag for this reason)? Should the close voters take their time to comment? Should we comment whenever we see a question caught a close vote irrespective of our agreement with the close reason?
