Frustratingly, I can't find anything in the FAQ which would indicate why the thread (and countless others) have been closed: http://programmers.stackexchange.com/faq
Questions which are similarly open ended and perhaps more subjective are still left open ( http://programmers.stackexchange.com/questions/99445/is-micr... ). If anyone has more insight into how/why questions get closed on programmers.stackexchange I'd love to hear it!
