You don't have to be a usability expert to recognize the name Dr. Jakob Nielsen. He's considered the Web usability guru, and is president of the Neilsen-Norman Group and author of Designing Web Usability: The Practice of Simplicity (and several other books). In eWeek's first online video in the Great Minds in Development series, Dr. Jakob Nielsen tackles the issues of designing for usability and how to maximize usability in the apps you build. In this interview, he discusses everything from the proper attitude for programmers (why being smart might be bad for your code), to the importance of prototyping in design, to the reasons why PDF, Flash and local search engines can hurt more than they help.
