Can we really improve on Clavius? An awful lot of good work has gone into it over a few years. Do you have any specific items in mind that it doesn't cover, or cover well enough? Would it be better to approach Jay about incorporating it into Clavius, or should it really stand on its own?
Lately I've been debunking some of the more esoteric engineering-related Apollo hoax claims, especially from Hunchbacked on Youtube. Fortunately, judging from his very low view counts I doubt he has much appeal to the average person. If I just put my responses on my own personal website, anyone who finds him in a Google search will probably also see me and realize that at least one engineer who knows this stuff strongly disputes him even if the gory details are obscure. I don't like appealing to authority even when I'm the authority, but it may be the best I can hope for.
I've been thinking of debunking Apollo denial as a sort of practice case for a much bigger problem: getting the general public to deal with important topics that are both highly politicized and extremely technical. Yes, every debunking effort must ultimately stand on the facts, which must always be made available. Ideally any interested person can understand them and draw their own informed conclusions. But that just isn't practical when things really get esoteric. I've had to come to terms with this in debates about global warming. I understand the basic physics of radiative heat balance but I'm by no means an expert on climate change. I don't have anywhere near the knowledge and expertise needed to independently evaluate the IPCC's conclusions, nor can I reasonably hope to get it. I just have to trust that the experts are following the scientific method and producing the theories that really do best explain all the data. It can be hard to persuade others to do the same when they're constantly overhearing direct and very well funded attacks on that entire branch of science. Like it not, experts do matter and so does their public perception.
