Chris Anderson: "what WSJ.com used to do was to offer a backdoor to free content for another class of consumer: the social media maven. Paying subscribers could make content free to others by clicking on an icon that created a URL for a free version of the story that they could use for blogging or to submit to sites such as Digg or Yahoo Buzz. ... The deal was essentially this: these often influential word-of-mouth generators could trade reputational and attention credits for free content. ... A very nice Freemium model, in other words."
