I like reading Douglas Bowman’s farewell post. He left Google after three years. Here’s a paragraph:
Yes, it’s true that a team at Google couldn’t decide between two blues, so they’re testing 41 shades between each blue to see which one performs better. I had a recent debate over whether a border should be 3, 4 or 5 pixels wide, and was asked to prove my case. I can’t operate in an environment like that. I’ve grown tired of debating such minuscule design decisions. There are more exciting design problems in this world to tackle.
Other comment about this farewell post:
This is, I believe, why Google’s products (many of which are great and innovative–I remain a devoted Gmail fan, for example) will always fall short of achieving the emotional connection that people feel to an iPhone. There’s no one with real power there who has a good sense of what makes a product beautiful or when it feels “electric.” You can’t quantify that sort of thing through study or harness collective brainpower to coerce it–someone just has to know it when they see it.
