We are overwhelmed by all the information coming at us in our daily lives. We need something that makes sense of the chaos, that orders and filters the information streams.
Personalization must be part of this vision. Search can help you find things when you already know what you want; personalization helps surface useful information when you don’t already know what you want.
Personalization offers a way to find focus. It learns what you like, shows you what you want to see, and filters out the rest. It extracts knowledge from the information chaos and helps you get the information you need.
