Personalized Search for Everyone

Google:

What we’re doing today is expanding Personalized Search so that we can provide it to signed-out users as well. This addition enables us to customize search results for you based upon 180 days of search activity linked to an anonymous cookie in your browser.

I suppose this makes sense, and even without cookies Google could figure out the history, but it still creeps me out. You can turn it off by clicking on “Web History.” SEO just became a lot more unpredictable.

Kindle Book Sales

Jeff Bezos (via Marco Arment):

For every 100 copies of a physical book we sell, where we have the Kindle edition, we will sell 48 copies of the Kindle edition.

That’s incredible, but I’m not sure that I believe it. Are the numbers skewed by averaging in the free Kindle books or something?
