Just to rub it in a bit further, lies have become an all too important part of our national (and world-wide) discourse. For example, Microsoft announced they made a study that showed the city of Munich didn't save any money by switching to Linux...but they won't release it.
Personally, I blame the internet. I mean, why not? But it's true, I think, that the internet--while giving all people a theoretically equal voice--has also allowed lies to be spread more easily.
This way, a company or an organization can spout nonsense like "Munich would have saved more money if they had paid us more money" or "piracy costs the entertainment industry $1 trillion dollars a year", and then later backtrack--but the meme is still out there. Most people just aren't very critical thinkers or readers, and the lies still spread over the water cooler.
