I noticed that this list question has +10 score But this one has -7 score
As far as I can tell from my reading, on this particular StackExchange site. List questions are not off topic (unlike some other SE sites)
Neither of the questions are particularly fantastic, (or particularly awful). What makes one better than the other?
The one with the poor score is far more definitively answerable. The one with the good score requires some quantitative thought (which I guess makes it more interesting).
