Book news
I have received all readers’ comments, and the book should become available later today. As one would expect (from what I’ve learned about usability testing), with four readers the comments I got had very little overlap. Usability tests usually involve 5-7 people—beyond that number, the rate of new findings drops off fairly quickly, but up to 5-7 provides much information with amazingly little overlap: different people really notice different things.
So: it’s looking good and I’m going through it one last time. 103 pages now, and close to 42,000 words.
