Google Search Customization Sans Logins

Minus ten points for me, I didn't even realize Google personalized the search results of people logged into their site. Now they're doing it for people who aren't even logged in via cookies.

According to the article, you can turn this feature off. I'm not sure if I will or I won't. For one thing, I have multiple accounts. I don't run my main email through the megducation address. Otherwise, I wonder if the same problem I have with Amazon's recommendations will come up. The recommendations are all well and good and sometimes useful, but should I happen to buy a book to send to my friend who likes vampires, I'm getting a lot of vampire-related book suggestions I really don't want.
