Can we exercise a little civility here? Why say this is a stupid thread? Why question why someone would ask a question? Just move on if it's not for you--that's my humble view.
Forums are digital quasi-equivalents of meeting places of yore. The righteousness of those criticizing posters is tiresome. I'd prefer a forum where negativity is rare and the free flow of thought (regardless of merit to the thought) is promoted.
I can think of a good chunk of reasons why someone would ask this sort of question.
