I think the comments under this answer stats.stackexchange.com/a/156787/82135 should be removed.

Apparently, I had already flagged them, so I can't flag them again.

I just think that if a comment isn't really useful, it should be removed.

I've commented in that thread, so strong declaration of interest. I think the comments are helpful and entertaining. They should stay!

If comments are useful, they should stay, but the ones I am reporting are not useful at all. They are entertaining. Maybe.

Entertainment is fine by me as a side-effect of intelligent and well-informed comment. The double meaning of "wit" as humour and intelligence is no accident.

But I guess one of the main goals of SE websites is to be useful and not lose time.

So, don't enter chat rooms then! (Insert friendly emoticon of choice, or not.) FWIW, it's public that I flag a fair amount but I focus on what I deem offensive or not nice (usually, moderators agree) and on what is now redundant (ditto). I don't think moderators (I am not one) are especially exercised about a little frivolity.

@NickCox I was talking about the main website. These chat rooms were created for a different purpose. I am not saying that this is a big problem, but they are unnecessary on the main website, IMHO

I am talking about the main website too. I am really active only on CV and SO and I have noticed a big difference in attitude to comments. On SO, comments are removed quite readily. On CV it is not unusual for comments to be as useful as answers and to have lasting value. I don't disagree that comments that have lost their good point or never had one should go; we just disagree, it seems, on where the line should be drawn.

I also noticed this different attitude.

Anyway, I do not want to start a war, but I like SE websites mainly because they are useful and not because they are entertaining. I just think that whatever isn't useful with respect to the original question should be removed (but not because it may not be entertaining)

Anyway, it isn't a big deal if they stay!

@nbro If I am reading between the lines correctly, I believe one point @Nick was making is that some of the entertaining comments are also thought-provoking and instructive. I found that to be the case in your example. I do agree that superfluous comments--those that are there just to make an irrelevant joke, for instance--sometimes have negative value and can be removed. The distinction may be a highly subjective one.
