I am really not trying to be funny or polemic, but I don't seem to understand why people are bothered with questions that are from users' homework.
Fair enough that we would like to encourage people to learn on their own, as this will make them learn a lot more, rather than simply giving them the answers; but put it this way: the fact that they are going to the trouble of asking the question is not an indication to wanting to find it out? It can perhaps be a very lazy approach, but nonetheless it is still better than people who do not bother doing their homework in first place. Also some of those questions, even though are from homework, are really good, so a lot more people would also benefit humongously from the answers provided. Plus, who really cares if that student is learning to his/her full potential? It's his/her time and money spent, but I, on another hand, just like many others who are really interested in learning as much as possible, will definitely look at the questions/answer and say: "actually that is very good!".
I can see that people may retort, saying that it is not fair to the university/college/colleagues. I would pose the question: "why not?" If the resource is available online and the student managed to find it, it is already something.
When I seem to disagree with what appears to be the majority's opinion, my first thought is that I am wrong and so I seek to find strong counter-arguments to make me change my mind. So I am just trying to figure out what the general rationale behind this topic is.
