Glenn Greenwald lays it out quite succinctly:
The tactics in the article are as intellectually lazy and empty as they are transparently deceitful and trite. There is no cheaper or emptier form of argumentation than to isolate a specific individual, describe her, and then, without any basis, ascribe those attributes generally to some larger group -- in this case, a much, much larger and more diverse group -- of which she is ostensibly a part. Anyone who has even minimal exposure to "the blogosphere" knows that it is insusceptible to the sort of sweeping generalization oozing from every misleading paragraph in this article.
The crude tactics employed by this article are easily dismissed, but the objective of this article -- to destroy the credibility of the blogosphere and what we do here, mostly because it is so threatening to the establishment media's dying monopoly over the flow of information, news, opinion and analysis -- should be taken very seriously. This is not some isolated hit piece. The Washington Post alone has published several articles in the last couple months which suggest, imply or outright state that the blogosphere generally, and the liberal blogosphere in particular, is irresponsible and filled with raged-driven radicals who are as extreme as they are irrelevant. Thus, one can and should ignore what it produces, because it is nothing more elevated than bitter, reckless, and hate-filled rants.
It is just astonishing to have to read an endless article from the Post about the supposed rage and anger on the "Left" -- all based on the sought-out, most extreme sentiments of people with little or no real influence -- while the eliminationist and traitor rhetoric that has been a central rhetorical tool of the Right's primary power centers for decades is mentioned only in passing, only by way of explaining how the Right used to engage in this sort of rage-driven politics until the Left took over. But anyone who listens on any given day to Rush Limbaugh or Bill O'Reilly, or who reads the hate-mongering and treason-accusing screeds of Ann Coulter, Michelle Malkin and Powerline, know how fundamentally false that picture is.
Any time old, crusted, failing, dying institutions launch attcks on new and innovative competitors, it is an unmistakable sign that the attacking dinasour feels threatened and feels its power slipping away. That dynamic, more than any ideological goal, is what is motivating the steadily increasing appearance of these types of hostile blogosphere caricatures masquerading as news articles. The reality is that the blogosphere need not be a hostile competitor of journalists, but can be a uniquely valuable research and analysis tool to supplement the governmental adversary role which journalists are supposed to perform.
