On a day that the Wall Street Journal posts on its OpinionJournal page a thought-provoking piece by Joseph Rago about the defects of the blogosphere, the newspaper also prints (for subscribers only) a letter from our Ed Whelan responding to a December 9 op-ed by Randy Barnett on the Ninth Amendment. Ed’s letter, of course, appears long after he and I both responded to Barnett within a day or two here at Bench Memos with substantially the same arguments. Still, Rago’s article is worth chewing on, and could prompt many bloggers, including yours truly, to do what we do better.
