"That is the reason we bought Flickr—not the community. We didn't give a shit about that. The theory behind buying Flickr was not to increase social connections, it was to monetize the image index. It was totally not about social communities or social networking. It was certainly nothing to do with the users."

Finally read it. Absolutely worth it.
