Roger Cohen misses one glaring point in his essay. Information from newspapers are the foundation for many blogs. By linking to the news items, people who don't read the papers have this information.
Bloggers are just making the "reporters" accountable for what they write or report on the air. If NY times did not provide a liberal voice for this White House maybe there would have been more questions about this fiasco.
News is no longer read on a street corner. Pamphlets are no longer a source of news. Rupurt Murdoch has finally purchased the Wall Street journal. He is more of a threat to Cohens profession then the netroots.
