Plus or minus in the number of comments on the topic?

Question

Habr

I understand that means "+N" - the number of new comments, but what does "+-1" mean, despite the fact that there is no new comment there.

Answer 1

Doesn't mean anything, just a glitch that can't be fixed for a long time.

Answer 2

maybe it means that UFO deleted 1 comment, and the difference between the past and current value is -1, and the plus is simply always drawn when there is a difference

Answer 3

UFO is up to something :)

Answer 4

The server cannot accurately count how many comments. So he writes like this, they say, count how much exactly =)

Answer 5

Interesting ... I also have, after viewing all the comments, what UFO on the page seems to be not observed

Answer 6

UFO arrived? :)
