Rosan: you shouldn't have to justify your stream of questions. They're entirely appropriate and have opened many lines of debate that cut to the very heart of what we collectively call design research. It keeps people on their toes and, hopefully, everybody learns something on the way. There's probably no better place to ask your questions than here, amongst researchers from all continents. A collection of very astute minds! I've been lapping it up (when I can) in between my professional design duties, trying to maintain a grip on the 'bigger pictures' in design whilst dealing with the day-to-day of designing products.
