Most people use computers mostly for information storage. Which means that most people do a lot of searching. My most common search is the Web as a whole, via either Google or Yahoo!, I try to switch back & forth from time to time. Next most common would be email via GMail, my own slow mailgrep, and maybe some year Spotlight. After that would be the Web Event Stream via Technorati (for me, text all the time, tags almost never). Bringing up the rear would be a certain amount of filesystem searching (Spotlight sort of works, except for my email) and grepping source code. I wonder if I’m typical?
