This system dosen't seem to have a way of taking into acount varying levels of skill in diffrent fields. For instance, if someone is an expert in a paticular field, and is right about questions that field a very large percentage of the time, and most of the time votes only on questions in that field, that person's votes will have a very large weight on all questions, even if he only is average in subjects other than in his own field. In this system, his votes will have a very high weight, as he is almost always right on the questions he votes on, as he nearly only votes on the ones he knows a lot about. Then he goes and votes on some things he knows nothing about, yet he still gets high weights on his votes. If he votes on many decisions in his field for each one he votes on in fields he knows nothing about, he will keep his high vote weight, and so will keep influencing some decisions (that is, the ones not in his field) far more than he "should".
