Why would stackoverflow delete a question that had answers and 6k views?

And the replies and comments surprised in the positive sense of the word. People made a real effort to answer this seemingly trivial question. And other people seemed to like it as well since after a couple of hours the question had almost 6000 views.

And then some moderator decided to remove the question. Which struck me as strange. Why do you think stackoverflow removed my question and do you think it is right?
