I love conspiracy theories, especially their debunking.
Following the (relatively) recent close-up mapping and photographing on the moon, the conspiracy theorists who believe that the moon landings were filmed in a Hollywood basement have pretty much shut up: http://spinor.info/weblog/?p=958
I am with Mark on this one, it is great listening to both sides of the argument but even more so when the conspiracy theorists have hard proof placed in front of them. Its amazing how quickly they disappear under the rocks they crawled out from to start spouting their ill informed nonsense!!
