The Big Web Split

Andy Boyd posted what may be the first sighting of Google providing auxiliary search results from the blogosphere on its main stream web search page. My thinking has always been that eventually, main stream search sites will have to differentiate social media, and especially blogs, from other web content due to the way in which link based static ranking works. Because linking is fundamentally different in the blogosphere (compared with other types of sites) the links must be interpreted differently, something which a simple structural algorithm like PageRank cannot do.
