This blog explores an idea I first posted on The intent is to create a ‘language of critique’ for user experiences. It was initially targeted at online user experiences but i’m hoping to extend it beyond that. I’m going to regularly post new examples of each characteristic and principle and i’m hoping for suggestions and contributions!
