It's old news now that Abu Muqawama, A.K.A. Andrew Exum, has retired from blogging (temporarily I'm sure). What I hadn't noticed, due to reading Abu Muqawama via Google Reader, was that the Abu Muqawama comment section may be in the process of jumping the shark. A couple months ago you had great comment threads like this one. Now you have a 90 comment thread where anonymous trolls yell "defeatocrat" at each other. "I RED DUG FEITHS BOOK AND HE SEZ UR WRONG!@!!!1" I imagine the blog's remaining authors are too busy with their actual jobs to monitor the comment threads, although Dr. iRack smacks a few fools down in that last link.
