The problem is hardly unique to this SE site, but for people new to the site there is fundamental knowledge that isn't obvious.
For instance, the "tour" page doesn't mention that questions must be set up so that they can be scored, independent of votes, nor does it provide a list of "scoring tags".
Similarly searching for "score" on the help page produces nothing useful.
That seems like a very important concept for this site, so why isn't it presented front and center?
One specific improvement would be if the question submission form required one of the scoring tags, the same as meta sites require one of a set of tags.
