This kind of thing drove me away from MOOCs for certain subjects. There was the Human Computer Interface course where your UI was graded by three peers. On multiple assignments I would get a strong positive with comments, a strong negative with comments contradicting the very things the other peer graded positive, and then a "good job". It was utterly useless feedback on things where feedback really was important for learning.
