Sometimes questions are answered to help give ideas for great hubs. Maybe we really want to know the answer and are hoping the question will prompt an expert to create a hub to answer it. The questions are great sources for very successful articles.
Some people answer the questions, but a lot of the questions are philosophical, and should be asked on a forum post. If people ask a question that can be answered (like this one) people will answer it. As for why people post all these unanswerable questions... I think it helps your hubscore to ask a lot of questions.
They start off by asking one question, but once they realize that no one's answering they shoot off another question, and so on. It's a vicious cycle...
May be its an old technique for building traffic to their hubs! Or they just unaware of "FORUMS". I still don't know the difference b/w 'need help...' topic in forums and this 'questions'.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
