FYI: the current about page has the "unicorns and daisies" default question.

@Iain: I think that's a 10k privilege. Hauke, fwiw, the proportion of 3k+ users to all users is about the same for U&L as for SF. And "Leave Open" reviews are roughly 1 in 5 on U&L based on a count of the last ~500 review actions. (Stack Overflow has over 50k questions in the close queue.)
