Post History

**I believe comments need some sort of mechanism to allow 'good' comments to rise to the top.**

Some posts attract a lot of comments. Sometimes they're a bit of back-and-forth clarification between asker and respondents, sometimes they're humorous, and sometimes they're mini answers in themselves. Naturally some comments (eg the mini answers or the clarification comment with a lot of detail) are far more important and relevant than others (eg the first two back-and-forth clarification comments). However the not-so-important comments aren't necessarily so bad that they should be deleted; they still have some relevance.

After five comments, further comments are hidden away under a 'Show x more comments' link. However the order of comments always remains the same. If someone comments a particularly useful bit of information as the sixth comment, it will always be initially hidden while less important comments are initially visible. It goes without saying that this isn't very helpful for future readers.

The comment system needs some mechanism to allow especially useful comments to be shown in those first five comments. An upvote system may be misused for funny comments, but if we look at the example of the SE sites, the system generally worked pretty well. Relabeling upvotes on comments to 'Me too' or 'Helpful' votes may further improve this.
