I agree, but I'm not sure that there is any other way to establish positive discourse -- for most posts there are the enthusiasts and the middlebrow detractors, and virtue may often only appear after both of these positions are raised and discarded in favor of an hopefully Aristotelean mean. This is also to say that appropriate discourse depends largely on the context (i.e. what has already been said on the topic), and not simply on a single right answer (as in the sciences).
