I found the context of personalize search really interesting. From the user’s standpoint, it is definitely helping the user out without any doubt. with each browser knowing and keep track of what a user’s preference is. That’s also my question, each user will have different habit of using a search, how can you as a developer cooperate that into the design and while developing a tool, like, how would you know which function would be more preferred by the users or not? Also the user profiles would be more for one specific type of users, does that mean you are not considering other users using habit? Thanks.
