Some are worried that the blogosphere will simply promote the lower common denominator to the exclusion of serious journalism or commentary. Alisa Harris quotes Eric Alterman saying, “And so we are about to enter a fractured, chaotic world of news, characterized by superior community conversation but a decidedly diminished level of first-rate journalism.”

Commenter Bob Buckles notes, “When a cow is milked, the cream rises to the top. So to, the best of internet ‘journalism’ will be the stuff that is aid attention to, unlike the professional ‘journalism’ of Dan Rather.” Naturally.
