using design to help usability
A great article that could improve the usability aspect of our page design as more complex interaction models used on the web: Communicating web 2.0 through design by Robert Hoekman Jr.
The main message that I learned from this article is to simplify the design, not only visually, but also in the way the content is articulated. Make it painfully obvious.
Another important lesson is to look to existing convention that have been widely accepted by users (i.e. how components of desktop application works). This will create familiar feeling for users and help them gain confidence in interacting with our application.
