Spam is a problem, but that's not the reason why we can't "retrieve" good information. That's just not how humans work. We are lazy. We grab either the thing we know or the thing that seems easiest / lowest risk. Hardly ever do we change our minds, even if a great product is available. We're very emotional and easily influenced by many distracting factors. Research is hard, and information is not easily available (and never will be). Marketing is in effect good communication. It's much more valuable than a good product, because we as humans are en-large lazy and good marketing bridges that. However, a good product plus good marketing are unbeatable. The Microsoft's and Oracle's of the world won not because they had the best product (they didn't), but because of great marketing.
