Social Indexing

摘要

Bret Taylor wants to make online services more attuned to what you really want. Search sites could take your friends' opinions into account when you look for restaurants. Newspaper sites could use their knowledge of what's previously captured your attention online to display articles you are interested in. "Fundamentally, the Web would be better if it were more oriented around people," says Taylor, who is Facebook's chief technology officer. To bring this idea to fruition, he is creating a kind of social index of the most frequently visited chunks of the Web.Many sites have tried to personalize what they offer by remembering your past behavior and showing information they presume will be relevant to you. But the social index could be much more powerful because it also mines your friends' interests and collects information from multiple sites. As a result, the index can give websites a sense of what is likely to interest you even if you've never been there before.
