Have you never heard of Comscore? They have (until Google beats them) the same offer -- web acceleration in exchange for total usage visibility. They can predict all sorts of stuff based on analyzing their data. Their internal statistics accurately beat national labor results by about three days. They can predict elections and American Idol results. This is the next business for Google. Feeding leading interest indicators to the companies, investors, and politicians that can afford it. It's not you that Google is interested in. It's a statistically valid representation of you.
