This is the first I'm hearing of it, and I imagine the first a lot of other people are hearing of it. Two things:
1. Just because it's old news, doesn't mean it isn't news for a lot of people.
2. My point still stands: some conspiracy theories do turn out to be true (do a search for "conspiracy theories that were proven true"), so wholesale calling conspiracy theorists nut jobs, or saying they are "tinfoil hat" wearers is unbelievably shortsighted.
