Your experiment is fantastic. I love writers like Terry Pratchett who can use complex and even obscure language while keeping ideas straight forward and simple — but it really does take a genius to do this. Perhaps if more people used a writer like this to start with and later edited in the more complex words — simply because they are more accurate, and NOT because they feel the use of the word makes them appear more intelligent, we would actually HAVE more intelligent people. The combination could be a winning idea!
Would you consider making a version for those of us poor souls who only have access to non-Mac computers?
