This week I got my first feedback to the paper I finished during holydays. Josef Scherer a Scrum consultant I met in the summer and became a dear friend, gave positive feedback: "I am quiet impressed by your paper! As a learned linguist and having strong interest in psychology and philosophy I must say that your point of view towards Domain Driven Design is very interesting. The 'mental model' as far as I experienced plays a role in user interface - I never thought it could be important for the application itself". This gave me some sunny days, I must admit. Still I don't think my paper is ready for public.. I will explain later why...
