Yeah but that presupposes that people give you best answer because you are right and not because you are saying what they want to hear. consequently, there are a number of posts in law where the "best answer" is legally nonsense........
Hmmm... that simply gives credence to those who win best, and nothing to those who offer not quite best but more often second place posts. I can think of 3 or 4 individuals who seem to be very helpful in their areas of expertise.
