In one question I've posted, there were a few comments upon my wrong capitalisation of a scientist's name.
Another user had already edited it, and someone else had negatively voted it (I really wish I could see the real and actual reason for them negatively voting, so that I could improve my questions), so now my title question has a shade lighter than normal questions (is it correct to assume that is how it is for negatively voted questions?).
However, I was completely surprised to see that now my post contains none of the comments that were there till yesterday. Can someone with a higher reputation points delete all the comments in the same way they can edit the posts, or is this a glitch?
