Late yesterday, Google announced perhaps the biggest change it has ever made to its massive network of web services: Starting in March, your search and surf habits across all of Google’s products will be combined to form the mother of all behavioral profiles.
On March 1, Search will know the contents of your email and the videos you watch on YouTube. If you use Google Docs for work, Search will know which company you work for and which industry you work in.
Via Google Reader, Search and YouTube will know what content you like to consume.
