Zelaron "disapproves" of more than four posts a day

The longevity meter skips a step. When you look at someone's join date, you really want to know: "How long have they been here compared to me." You see your longevity on every one of your posts, so when you see theirs you have an instant comparison without any math. You can always mouseover the longevity if you want to know the actual join time.
