Four observations: (1) I view it as my duty to play with beginners a little, although I often remind tham that it is better to make a mistake than to play too slowly, (2) I do think that once someone has logged in 500 times or so they should be required to post at least a simple card, (3) I think that BBO could help the learning process by, when it sees a player with horible results, sending them a link to the SAYC summary, to a learning opportunity or something like that (BBO knows how good and bad players are from their cumulative results, and the law of large numbers does apply), and (4) I wish that BBO posted game completion percentages so that hopper would be encouraged to complete the hand befor hopping off.
