What does this mean, exactly? I get social media is how the results of journalism get distributed, but what funds the journalism itself if traditional news/media companies go out of business? Is twitter or facebook going to fund investigative journalists? What's the business model for a company looking to pay people to research and write about things if 'social media is the new journalism'? Do we rely on non-profits/donations? Or are you proposing we'll get all our news in a decentralized manner via people posting what's going on around them?
