I said on my blog that re the Apollo Hoax, the geeks won -- and everyone should have seen it coming. The hoaxies challenged the internet, and when given choice of weapons foolishly went for "Science!" And if the interwebs breeds nothing else it would be tech-savvy, argumentative science nerds with a thing for space.
The only time they manage to make headway is when they keep it murky, political, and emotional. But there are a lot of more interesting murky, political, and emotional conspiracy theories competing for eyeballs -- on this arena, the Apollo Hoaxies lost to, well, Cthulhu.
(Timely illustration; Chrome's spellcheck stumbled on "Sibrel" while I was composing this post, but it easily recognized Old Squid-Face.)
