Can someone please explain the philosophy of stackoverflow and why such questions get upvotes?
Whatever the philosophy, questions and answers are upvoted and downvoted by whoever wish to do so, for whatever reason they fancy. I can upvote a question just because I like the way it is written; or simply because the poster is new to the website and I can give them a few reputation points so that they can comment; or because they made a joke that made me laugh; or because, however stupid it is, their problem had been my problem many years ago; or because I think that, anyhow, the poster might be a kind person because he or she wants to be courteous to their teacher; or ... yes, we can go on forever.
Is it appreciated that people shutdown their brains and get totally paralyzed until someone tells them how to do thing?
Random thoughts below:
When I was a student at high-school, we used to assemble tube circuits powered from 500 V supply voltages on unisolated bread boards, so that every now and then a student could get the thrill of an electric shock.
When I was a student at the university there weren't (almost) any university policies. It was just student against professor. If a professor wished to fail you because you, guy, were wearing an earring, there wasn't anything you could do; a professor could throw chalks to you because you were chit-chatting during a lesson; or they could take pictures of the class just to see at the exam if you skipped a few lessons; and the fact that a professor used to yell at students was, well, taken as normal.
It can't be denied that proceeding, or barely surviving, in such an environment required students to turn on their brain. However, modern safety rules (what about the "it's hot" band around the coffee cups? what about the "don't put the cat in the washing machine" warning?) and university policies forbid all the above niceties to protect people from electric shock, harassment, discrimination etc. Do you consider this a bad thing?
The price to pay -- of course there's always a price to pay -- is that people nowadays has become more cautious about doing things that can possibly break a rule. And so, yes, with the fear of doing something wrong, people sometimes ask questions whose answer seems pretty obvious to others.
That said, as my most voted comment highlights, sometimes I'm puzzled too.
