Those that do seem to speculate about “applying your social network to search” and other exotic stuff, but I’m thinking of something far more basic than that: users.
That’s right, users.
Now, I know what you’re thinking. “Google has millions of users!” Of course they do. How much do they really know about those users? Do they really have a user database from which they can mine interesting data? If they have one, it must pale in comparison to what Yahoo, AOL, and MSN have.
