Yep, I agree on the whole. The problem that I've seen in a lot of cases is that the resources that collect knowledge and display it on the web don't necessarily incentivize the knowledgeable to contribute or reward them for doing so in the best possible way. What you end up with is a high signal to noise for quality, factual content, and for things where facts are not even expected (politics, etc...) you often end up with a polarity that doesn't acknowledge the other side exists. Beyond all that there is a huge amount of sarcasm, humor and nuance to content that will be hard for a machine to figure out on its own, but hopefully you can find a way to separate the wheat from the chaff :)
