Having successfully become our personal librarian, Google now wants to be our personal oracle. It wants to learn all about us, know us better than we know ourselves, to transform itself from a search engine into a psychoanalyst’s couch or a priest’s confessional.

The next stage is a personalized Web service called iGoogle, a tightly-knit suite of services — personalized homepage, search engine, blog, e-mail system, mini-program gadgets, Web-browsing history, etc. — that together will create the world’s most intimate information database. On iGoogle, we all get to aggregate our lives, consciously or not, so artificially intelligent software can sort out our desires.
