I think that your idea would work, but instead of a week, it should be four days, because that's the period it's regularly up. Also, when that happens, it should be like "renewing" the question, in that it goes back up to the new questions page. However, there should be a limit just like renewals to stop people from endlessly doing that.As well, people could have their questions extended if they draw a lot of attention.
Maybe something like for every 10 answers or 100 views, they get an extra day. That way popular questions could stay around longer.
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.
