This whole article only makes sense when one restricts one's scope of the web to "social web". The notion that Facebook and Twitter contain the web's most valuable information seems ridiculous otherwise. Except for information on trending current events, I personally almost find the opposite to be true: Facebook and Twitter add lots of noise and little information compared to what can be found outside of them. Posts on Google Plus are more likely to be interesting to me than on Facebook, and blog posts tend to be still more interesting than Google Plus posts. My impression is that the further away I move from the walled garden "core" of the social web (Facebook/Twitter), where everyone feels obligated to add his chatter to the general noise, the more valuable the content becomes. As long as Google is able to decently index the complement of these walled gardens I see little reason for despair.
