I am VERY skeptical that this actually works, but it is an entertaining tool nonetheless.

Microsoft has released an online Adcenter tool which can "predict a customer’s age, gender, and other demographic information according to his or her online behavior—that is, from search queries and webpage views."

"flower" is a female oriented search query with a 65% degree of confidence. "Sex" is male oriented search query with a 60% degree of confidence. "attentionscan" produces, not a surprise: "unknown".
