Interesting insights by Steven Levy into Search, plus Your World. Here he talks about the way Google designed the Search page:
[..] The company has spent its entire corporate life protecting the integrity of its search product. When writing In the Plex, I learned that the secret behind Google’s somewhat bland design was that if Google looked like it was designed by a machine, users would implicitly understand that Google search itself was unpolluted by strong opinions. Google meticulously positioned its flagship product as a neutral judge of what was relevant to the user.
I hadn’t thought about it this way before, but this is exactly what Google’s Search page design communicates to me. “A neutral judge of what was relevant to the user”.
