Thank you MaryAnn. The thing I think I notice, it is hard to say what is actually going on, is that the majority of people will not fully commit to offering criticism if there is a belief that I worked hard or have an emotional investment in a drawing or rendering. It seems that people are far more kind than popular wisdom suggests.
My bosses and colleagues constantly push me towards online collaborative tools but each of them have the ‘stench’ of professionalism — my experience is that while those drawings may look great they do little to stimulate meaningful discussion.
BTW– my wife is an elementary school teacher and we often visit the school in the “off” hours to look at the drawings posted in the hallways; hard to walk away with a frown 🙂
