I fail o see why [this question][1] has been closed as "Not a real question" - it is an interesting question, has upvotes, 4 good relevant answers and is on-topic.

More broadly, I'm a bit concerned that once a question gets the first "close" vote and gets into the review queue (which may or may not be fair for this question as it was a bit vague initially), it is much easier for it to accumulate another 4 close votes - people may be just agreeing with the previous voters without carefully considering the question itself.
