What he misses in this analogy is that part of what produces the "blur" is the superimposing of many relevan paragraphs found on the web into one. This mechanism can be very useful, because it could average out errors and give one a less one-sided perspective on a particular issue. It doesn't always work like this, but hopefully it will more and more. Also, even more useful is to do a cluster analysis of the existant perspectives and give a representative synthesis of each of these, along with a weight representing their popularity. So there's a lot of room for improvement, but the potential in my opinion is there.
