C|Net has an interesting story contrasting the cultures inside Yahoo & Google. The first three paragraphs show the most striking difference to me:
On the walls of Yahoo’s modest Silicon Valley offices there are posters with sketches of oddball inventions that have landed patents, such as a portable bird cage. The point: If a bird cage can get a patent, Yahoo’s employees can come up with something big if they put their minds to it.
The posters are promoting a program called the “Idea Factory” that is supposed to goose inventive thinking at the 10-year-old Internet-giant-turned-media-powerhouse. Through Idea Factory, staffers are urged to submit notions for improving everything from the company’s products to its campus.
Five miles down the road at offices of archrival Google, inventive thinking is assumed. At Google, engineers are expected to spend one day a week on a project of personal interest. It’s a mandate that’s spawned new services such as Google News, which now attracts 7.1 million visitors per month, according to Nielsen NetRatings, and the social networking site Orkut, which has yet to be integrated into the search site.
Yahoo puts up posters asking people to come up with new innovative stuff to help the company, Google gives both time and money to do so.
