"It may seem strange to imagine the blogging community as a force that will shape the information environment almost as powerfully as corporate media. We learn in the history books about Samuel Morse’s invention of the telegraph but not about the thousands of operators who shaped the circulation of messages, about Thomas Paine’s Common Sense but less about the “committees of correspondence” through which citizens copied and redistributed letters across the colonies, about the publication of Harriet Beecher Stowe’s abolitionist blockbuster Uncle Tom’s Cabin but not about the teenagers who used toy printing presses to publish nationally circulated newsletters debating the pros and cons of slavery. In practice, the evolution of most media has been shaped through the interactions between the distributed power of grass-roots participatory media and the concentrated power of corporate/governmental media."
