About usable web design. Krug says yes. He advocates general navigation as a means to present the entire site on all pages. While I enjoyed Krug's clear arguments I also disagree.
General navigation provides unrelated opportunities that add confusion to the user experience.
It is true that search engines, affiliate sites, and emailed URLs make an increasing number of users go directly to pages deep within the website. Still, this is no argument to confuse users through the option overkill created by general navigation. Despite this smaller disagreement I highly recommend the book. Thanks to Mark Da Cunha for recommending the book. For two reasons.
