Instapundit's headline:

"THE SELF-CORRECTING NATURE OF THE BLOGOSPHERE: REVEALED."

Actual story: Rittenhouse review got something mildly wrong, was called on it, and corrected it.

Relevance to legitimate critiques of self-reinforcing "echo chamber" effect of the "blogosphere": Zero.

Instaman's simplistic "blogosphere" cheerleading and utter avoidance of the real issues of bias in this medium leading to excessive "fact checking" in one direction and little-to-none in the other: Off the chart.

(And for that matter, what's with all the drive-by postings to Atrios' site, along with my own? You'd think that if Glenn thought the post good enough to comment on, he'd find it good enough to either link to or at least return to more than once. Apparently not.)
