One of the teachers in my judo class is a national level referee and he took time today to go over the latest rule changes. Most of them do not bother me, I'm not a competator anyway, and in randori at the dojo I attend we don't worry about them. I do hope however, that the IOC, and whatever Judo organizations are involved, spend adequate time educating the referees on the rules. The ref's at this year's olympics sucked donkey balls to put it lightly.
