Why Users Fail

On Page 132 in the book “Prioritizing Web Usability” by Jakob Nielsen, it talks about the problems users have with websites. I strongly agree with the statement “Search and information architecture are larger factors in task failures” (Neilson 133). The user cannot find what they are looking for when they have trouble navigating the site and trying to find the information. What is your input on this? I really think that websites should just be plain, simple and straight to the point.
