Hi Lars
Looking around I don't see a lot of people "down-rating" low quality content. Usually even the worst stuff gets some 5-star ratings from someone and nearly nobody sets low-star ratings.
That's the difficult bit - must be the human nature side and upbringings where a lot of us are taught 'if you don't have anything nice to say don't say anything at all'
I hope quality outshines quantity. But we do need a way for freshers/juniors to join SCN and learn so one day they are in a position to contribute to quality material (by then they will not longer be a fresher).
Regards
