Khoi Vinh is the design director for the New York Times online. He has written a tremendous piece about the state of online design criticism that mirrors my assessment of the state of online teacher criticism down to the last word:
Sometimes I wonder, then: given that everyone in design seems to more or less know everyone else, are we really having the kinds of meaningful, constructive, critical discourses that we really should be having? Are we too quick to take offense at the opinions of our peers? Or are we pulling our punches too much when discussing the merits of the work that our peers turn out? To put a finer point on it: are we being honest with one another?
