What is the purpose of "comment compression" (don't know what else to call it) on threads? Let's say you post on Shave of the Day. Your post pops up, and the few posted just before yours are there too. But then there's a gray bar (on my theme) which says there's are more posts, click here to see them. When you click on it, you're warped back in time a full day or two -- perhaps several dozen posts -- when all you wanted to see was the posts before yours and to proceed backwards at your own pace. Maybe it's just me but I'm baffled by the point of this feature. On a 1-10 annoyance scale it's a 1, but it's bugged me for years and I just don't get it. Can someone explain? Thank you.
