One of Reddit's cutesy error pages (presumably for Internal Server Error is similar) is an illustration that says "You broke reddit". I know it's a joke, but have wondered what effect that might have on a particularly anxiety-prone person who takes it literally and thinks they've done something that's taken the site down and inconvenienced millions of other people. Seems a bit dodgy for a mainstream site to assume all of its users have the dev knowledge to identify a joking accusation.
