Google is not important because it has all the information - it's important because it has hardly any. A major complaint is that there used to be good free reviews of commercial products that could be easily found. That is not "all the information". Information about the current round of commerically advertised products is something like 5-10% of all commerce (or less). And we are entering a world where "all the information" is what we do all day, what we say, how we react to different stimuli. That is the real review sites - why do people take this train and not that, why is that park safe and this one full of muggings. We need to solve the Google problem not because we want blogging like it's 2009 but because epidemiology is about to open humanity's eyes. And it's going to hurt if we don't make it free and open.
