Charlie Beckett's book, Supermedia: Saving Journalism So It Can Save The World, is a strong look at the emerging pro-am culture of reporting. He's not big on nostalgia --- there never was a golden age of trust, he notes --- and he asserts that relevance is perhaps the ingredient most significant today.
Beckett, the director of the Polis initiative, finds it frustrating that online and traditional content both are inferred as trustworthy and reliable. He opts to eliminate distinctions between old and new media, seeing that comparison as more of a reference to an elite framework.
