Preface: About this edition
People come and go so quickly here!
DOROTHY GALE (JUDY GARLAND) IN THE WIZARD OF OZ (1939)
I wrote the first edition of Dont Make Me Think back in 2000.
By 2002, I began to get a few emails a year from readers asking (very politely) if Id thought about updating it. Not complaining; just trying to be helpful. A lot of the examples are out of date was the usual comment.
My standard response was to point out that since I wrote it right around the time the Internet bubble burst, many of the sites I used as examples had already disappeared by the time it was published. But I didnt think that made the examples any less clear.
Finally, in 2006 I had a strong personal incentive to update it. But as I reread it to see what I should change, I just kept thinking This is all still true. I really couldnt find much of anything that I thought should be changed.
Half of the royalties for the book were going to a company that no longer existed, and doing a new edition meant a new contractand twice the royaltiesfor me.
If it was a new edition, though, something had to be different. So I added three chapters that I didnt have time to finish back in 2000, hit the snooze button, and happily pulled the covers back over my head for another seven years.

2006
(Writing is really hard for me, and Im always happy to have a reason not to do it. Give me a good old root canal over writing any day.)
So why now, finally, a new edition? Two reasons.
#1. Lets face it: Its old
Theres no doubt about it at this point: It feels dated. After all, its thirteen years old, which is like a hundred years in Internet time. (See? Nobody even says things like in Internet time anymore.)
Most of the Web pages I used for examples, like Senator Orrin Hatchs campaign site for the 2000 election, look really old-fashioned now.
Sites these days tend to look a lot more sophisticated, as you might expect.

Recently Ive been starting to worry that the book would finally reach a point where it felt so dated that it would stop being effective. I know it hasnt happened yet because
Its still selling steadily (thank heavens), without any sign of slowing down. Its even become required reading in a lot of courses, something I never expected.
New readers from all over the world continue to tweet about things theyve learned from it.
