Scenario: Ask a question. Receive several nearly identical, acceptable answers. Next day: Wanting to accept an answer, the thought is to click on "Oldest" and choose a "winner" by the obviously fair metric of who was first to answer..
No Sort Indicator. A cheap and easy solution?… ANy kind of visual indication as to whether the oldest, or in fact the newest posts are indeed, On Top. Without a context… a decoration of "old" is meaningless.
Recent posts exhibit an odd behavior - that I guess by nature of them having a "friendly" "relative" timestamp.. do not in fact show the time of the post.
This makes it very hard, within that period of time (from a few minutes after they post.. to a few days after they post) to discriminate the chronology of the answers. Am I nitpicking? Yes. But if this site had a slogan.. it should be "Nitpicking, now that's meta."
