I know that the official policy of Joel/SE is that comments are ephemeral and subject to unlimited deletion at a mere wish of a moderator.

However, I feel that deleting comments - which leaves ZERO backup of the comment data behind - is a very unthoughtful and ungratious thing to do to the users.

My problem is not with the deletion per se, but with the fact that the commenter(s) may have - as I have been known to do - spent HOURS researching material and polishing wording to put into comments. Wiping out that effort with zero option of recovery is basically a sound slap in the face of a person having spent the time and effort.

If possible I would request that the moderators adopt one of the two approaches, when deleting a comment thread that is not 100% clearly filled with junk only:

  1. Somehow back up the data in the comments (by forcing into a new chat room? I'm not familiar enough with SE tech to know if there's a good solution).

    This need not be permanent - again, only a temporary backup to make sure people who put in the effort in compiling research and wording can recover it, to post as an asnwer/edit/question/blog post/whatnot.

  2. Warn the commenters that the thread is about to be deleted, allowing them to back up the data.

    I realize that some comment threads are in possible need of an ASAP cleaning (e.g. when they degenerate into offensive language/name calling etc...). But a vast majority of threads that are deleted are merely "too discussiony", and not real-time-offensive, therefore allowing a grace period before deletion shouldn't be problematic.

    BTW, this is not an exaggregation. I had a comment thread that had at least 2-3 hours work of mine get wiped out on another site, because someone else was not being nice in the same thread.

    Technical note: Deleted comments are available to moderators, if something truly valuable was lost when a comment was deleted we can retrieve it. We can't undelete the comments, but we can certainly recover the content if need be.

    @YannisRizos - Thanks, didn't know that. However, unless there's an official policy that such requests are welcome, I'd feel like a complete jerk if I had to bother a mod to retrieve my comments any time I need to decide if they are worth salvaging as a separate post :) [ first, it gives extra work to the mod, and second, it makes me sound like I want some special privilege at the cost of that work ]. If the policy gives EVERYONE equal access to deleted comments, it seems a lot better.

    I elaborated more in my answer, but it's beyond silly to put hours of work in to a comment thread. If you need to have that much of a discussion do it in chat or on some other forum. Comments on a question or answer are NOT the place.

The very effort that is being placed into comments would, most likely, be better positioned in an actual answer, rather than in comments. Comments are intended to be disposable - they are post-it notes.

More importantly, comments are, to the best of my knowledge, not indexed by google. As such, to the rest of the world, they don't exist.

For these reasons, a rebuttal answer is to be preferred to a comment. A comment is supposed to be for inclusion in a post. If it is not being accepted, a rebuttal post (even one which pulls similar facts as the original) is to be preferred.

  • FYI - There was a meta thread on SFF.SE recently - plenty of people owned up to posting comments when they don't feel that they have enough for a good answer. This is likely doubly true here.

    BTW, this is exactly what happened here recently - I posted a comment (BECAUSE I felt the info wasn't thorough enough for an answer), was told to make it as an answer, and then immediately criticized that that answer wasn't up to snuff. In a fairly rude form, too.

  • Also, on History.SE, I was at least once chastized when i took a rebuttal would-be comment and posted it as an answer for "putting rebuttal in an answer". >:)

It sounds like you already know that comments are considered disposable and impermanent, so it seems silly to me that you would write something so important as a comment.

I always think of comments like a construction I build on a beach at low tide. I'm not going to build anything too crazy because I know it very likely will get washed away in the near future.

The whole point of a comment is to clarify or seek feedback on something in an actual post. I get the impression that if you are researching and thinking through your wording very carefully that you are using comments as a discussion forum, which is anathema to their purpose and the Stack Exchange network in general.
