Here is your must-read for the month. Here is your oh-my-God-I'm-sending-this-piece-to-every-smart-person-I-know hunk of outstanding, distressing, disquieting media bliss. Here it is: an absolutely exceptional inside scoop on the white-hot world of Sept. 11 conspiracy theories, writ large and smart by Mark Jacobson over at New York magazine, and it's mandatory reading for anyone and everyone who's ever entertained the nagging thought that something -- or rather, far more than one something -- is deeply wrong with the official line on what actually happened on Sept. 11.  See, it is very likely that you already know that Sept. 11 will go down in the conspiracy history books as a far more sinister affair than, say, the murky swirl of the Kennedy assassination. You probably already know that much of what exactly happened on Sept. 11 remains deeply unsettling and largely unsolved -- or to put another way, if you don't know all of this and if you fully and blithely accept the official Sept. 11 story, well, you haven't been paying close enough attention .
