Over the years (and there have been several of them), I have noticed an issue with comment moderation and the subsequent flow of discussion in the comments, and its getting worse.
Its really really annoying to come across relevant discussion in comments where you have replies to someone but you cannot see the original comment being replied to - this can have huge knock on effects, as you have to assume some context from the replies, which means assuming that the replies are correct.
Having had a similar issue with one of my own comments today (it simply disappeared overnight, but replies to it still exist without any context at all, and its not obvious what my comment was), this raises another issue - why was I not notified that my comment was removed? Did someone have an issue with it? etc etc etc
This is a problem across all of the SE sites I am active on, and as I noted above its only getting worse - has anyone else noticed this?
