For ad targeting, Google can collect the data it needs from the subjects of people’s Web searches and the content of email, but that data isn’t nearly as personal and valuable as the stuff people willingly provide to Facebook every day Isn't this statement getting fairly resoundingly proven wrong by advertisers? Facebook has some great demographic data, but Google Searches tie directly to purchasing intent. As an advertiser I'd rather know someone was searching for "mini vans" then that they're a married person with 2 kids. Everyone keeps touting Facebook's social graph data as its killer product, yet it seems that Facebook has struggled a bit to really turn it into a revenue stream on par with Google's search data.
