Also, the tooltips on the timestamps make no sense. I'm not a fan of the "x hours ago" style of relative timestamp, and much prefer to just know the actual date and time an item was posted. Some sites, such as reddit, give you an absolute timestamp in a tooltip when you hover over a relative one, e.g. hovering over "2 hours ago" on a reddit comment produces a tooltip that says "Mon Jan 21 12:15:37 2013 UTC".

But hovering over "about 2 hours ago" on a Designer News post produces a tooltip that says "20 minutes ago". What's going on here?
