The 9/11 "truth" movement has peaked and is currently stalled. It will eventually settle down as just another fringe belief system endlessly hyped by its followers. The online success of "Loose Change" was the peak for the movement. The independent "documentary" was the best chance the 9/11 "truth" movement had for the message to reach a broad audience. But the attempt to take "Loose Change" into the mainstream has gone nowhere as its makers are bogged down in the editing process trying to clean up the factual mess they made.
The 9/11 "truth" movement is no longer growing and it will not enter the mainstream consciousness as a serious alternative to the "official story."
If "Loose Change" ever gets a theatrical release [and that's questionable] it will be a box office bomb, symbolic of the movement that inspired it.
Face it, truthers, it's time to get a new hobby.
