Why is the snake oil topic closed?

By the way I agree with those who call for civility.  These are not life and death debates.  I'd like to think of the Audiogon crowd meeting for a drink at a bar with a good, eclectic DJ.  

I took the Pepsi challenge long ago...I could tell right away that the drink served warm and flat was Coke and that the cold fizzy one was Pepsi...

That's what happens when you eat at a dump. They serve Coke warm and flat. Which is analogous to naysayers who don't have good luck with certain tweaks. It's an operator error. Hel-loo! For the rest of the tweakaphobes, the ones who never get up off their Barco Loungers to try anything, who knows why they get a bee in their bonnets. Oh, well, you can't save the world. 

the challenge was presented by Pepsi - it was rigged of course...
