Folks that I have worked with whilst on consulting engagements may remember that I have mentioned Inductive User Interfaces (or IUI's) from time to time. I fell in love with inductive user interfaces when I read this old article on MSDN. However, thanks to the joys of RSS I have now been made aware of a new article by Mike Weinhardt called "IUIs and Web-Style Navigation in Windows Forms, Part 1".
Unless you have been living under a rock you are probably aware that Longhorn includes an interesting navigation model, but there are things we can do now to make our applications more inductive as opposed to deductive.
This article is definately worth reading, especially if you want your users to love you. Mike is an Aussie and also has a blog (subscribed).
