I dont have access to that diary =/ but i'm not a 9/11 anything either, so I doubt i'd have had a useful response! haha
That's really weird, because I found it on the reader's choice page. Anyway he mostly seemed to be a bit of a hothead spouting conspiracy theories and pointing out who stood to make money from the whole thing and how they weren't investigated. Also he was really stuck on the towers collapsing "due to fire," when evidently towers don't do that? Who knows.
I, also, couldn't load the page - but I saw a documentary about a year back that was all about the 9/11 conspiracies. From what I gather, they're pretty crazy - and not very accurate. I also think it addressed the fire aspect, and the fact the common claim was leaving something out? I don't really remember... if it interests you, I'm sure there's more info out there. :-)
