This came up during debugging, but would bother me, and other people to, I guess - It's not very informative to see dozen of comments to some discussion dated as "1 year ago", even though there're spread over months. So, it would make sense to have a duration limit for "human-readable" date application (a year, a month...) and show ISO date if longer than that, or just provide per-user preference to show dates in this or that format.
