Data, Not Design, Is King in the Age of Google

Right but that's not what Google is doing, they listen to what users do. This is not the same.
As Nate Silver says, predictability = designability. If you can predict which elements will elicit a certain reaction from a user, then you can design an experience to elicit that reaction. Data isn't optional in design, it's the sine qua non. It's not a coincidence that design is a synonym for fate; without data design doesn't exist.
Obviously testing major design changes with any of their core products is going to take alot more than a designer or two saying this or that design is better. I'd imagine the design process for smaller and new projects is much more open to changes on a designer's whim.
seriously? the placement of that search box and trending list really set the world on fire. i'm not really hating on twitter, but common - a search box and a list of data on the right margin? they should have mentioned the saved searches. better yet, bowman should have landed with twitterrific, twhirl or tweetie.
Designers should be free to create something innovative, but I see no problem with judging the results with real metrics.
But of course google is in the data business they are not in the design business so you can't really blame them.
