The intro just gives an idea of what the book is all about. Chapter one in the book talks about simplifying a Web site interface. Krug's first rule is “Don't make me think”. When it comes to a Web site, make it self-explanatory. Don't make people ask themselves why something is on the page. The information and graphics should relate and make sense as soon as they see it. Names, phrases, links, buttons, etc., should all use simple ideas and be easy to understand. Make them stand out as a usable part of the interface and not just information on the page. The site won't be perfect, but you want to get as close to obvious as possible. After obvious, move to self-explanatory. The main idea here is in order to have an effective Web site, the page has to “work it's magic” at a glance. Chapter two talks about how people view Web sites. He gives three facts about real-world Web use. Fact 1: we don't read pages. We scan them. Fact 2: we don't make optimal choices. We sactisfice. Fact 3: we don't figure out how things work. we muddle through. The main idea in this chapter is about why you should make an interface simple.
Overall, these chapters start to help me understand how people view and use Web sites and the psychology behind it all. I like some of the stories, and the info-graphics are useful too.
