A question was asked which was (deemed to be) not constructive. This was true of the way in which the question was asked.
But the question itself was (in my opinion) quite interesting, and I have wanted to know the answer for a while myself.
Unfortunately since I am not the OP, I cannot edit the question to make it more constructive and have the question re-opened.
Incidentally, I was asking my own question on the topic when I saw the (closed) question as related...
Is it possible for me to ask a similar question (hopefully in a more constructive manner)?
Quite interestingly, the said question has a wonderful answer, which the OP has un-accepted. What is the etiquette and/or rules of doing this?
