Don’t Make Me Think, Revisited A Common Sense Approach to Web Usability, Steve Krug – 2014
Design your site to be usable. This book will convince you in 5 minutes how critical it is to design for usability, and in another 55 minutes (or so) you will know how to do it. It is a pleasure to read the book, so 60 minutes will fly by.
Krug originally wrote this in 2000, and warmed it over in 2006. Now in 2014 he has added a look at mobile clients, and how that affects usability.
