T. Greer of Scholars Stage, whose writing about the unfortunate decline of the blogosphere in the face of social media I have linked before, notes a reaction to the Harper’s letter which grants no credence to the idea of “good faith debate”. Greer calls this The World That Twitter Made, giving the reasons why it caused that shift vs blogs.

In the same post where I previously linked to him, I also linked to Andrew Gelman on the relative merits of the two mediums, and he’s got his own reaction, but this time to an actual column rather than a tweetstorm. Gerlman often returns to certain “zombies” on his blog who retain their positions despite publishing falsehoods, but he’s not entirely satisfied when someone like Marc Hauser loses their job either as long as other prominent people stick up for them in their other endeavors. For my own part I agree with commenter “gap”, who notes that whatever Brooks’ demerits in not responding to criticism, he hasn’t tried to quash it either, so there’s nothing wrong with him adding his signature. I also think Gelman’s irritation at Pinker overlooks the “social media” part of Pinker’s objection to “social media pileons”, since, as even Gelman himself noted, blogs like Gelman’s are very different from social media.
