rethinking book tours

The Wall Street Journal had a really interesting article this week: "Rethinking the Familiar Book Tour". Is the traditional book tour in which an author reads his/her work becoming a relic of the past? Certainly folks' attention span is much shorter than it used to be. As a reader, I'm not sure I'd miss these traditional readings. They can be a bit dull, even when I really enjoy the work. As a writer, I'm not sure I'd miss these traditional readings. They can be a bit dull, even when I really enjoy the work. :) Besides, I can joke around and give a powerpoint presentation with the best of them!

What do you think? Should book tours/readings change? To what?
