Jakob Nielsen, Ph.D., is a retired principal and co-founder (with Dr. Donald A. Norman) of the Nielsen Norman Group. Jakob established the "discount usability engineering" movement for fast and cheap improvements of user interfaces and invented the heuristic evaluation method.
Frames break the unified model of the web and introduce a new way of looking at data that has not been well integrated into the other aspects of the web.
How to design websites for universal access, including users with visual, auditory, motor, and cognitive disabilities. Using good ALT-text only gets you so far.
Subsites can be used in hierarchical information spaces to give particular prominence to a certain level of the hierarchy which is used as the subsite designator.
Slate fails due to its inability to adjust to the online medium: too long articles, too little hypertext, scrolling home page (though redesigns have improved later issues)
The unprecedented international exposure afforded by the Web increases the designer's responsibility for ensuring international usability. Because of the myriad of issues in international usability, I recommend doing international usability testing with users from a few countries in different parts of the world. No guidelines yet published are sufficiently complete to guarantee perfect international usability, so an empirical reality check is always preferred.
The file system has been a trusted part of most computers for many years, and will likely continue as such in operating systems for many more. However, several emerging trends in user interfaces indicate that the basic file-system model is inadequate to fully satisfy the needs of new users, despite the flexibility of the underlying code and data structures.
