In the past year I have often been asked why I don't have a blog. My answer was always that I write so much, already, that I don't have time to write anything else. But, as should be obvious, I've now changed my mind. I have come (belatedly) to the conclusion that a blog can be a very valuable supplement to my books and the writing I do for the New Yorker. What I think I'd like to do is to use this forum to elaborate and comment on and correct and amend things that I have already written. If you look on my website, on the "Blink" page, you'll see an expanded notes and bibliography, which mostly consists of copies of emails sent to me by readers. Well, I think I'd like to start posting reader comments for everything I write, and this is a perfect place for that. There are also times when I think I've made mistakes, or oversights, and I'd like to use this space to explain myself and set things right.

The business of being an author has changed considerably over the last ten years. No longer is it sufficient to write a brilliant manuscript and manage to get it published. Authors now need to be excellent promoters of their own work. And for the intrinsically shy, that can be problematic. But an Internet trend has the potential to revolutionize author marketing, even for those who despise public speaking: blogging.
