Matt Cutts: one of 2011 strategies should be Social Media
Matt Cutts answers questions on the GoogleWebmasterHelp channel. In this question he answers a question about what to do with your strategy in 2011. He names the obvious ones: speed, control of the CMS, internal linking and internal education. But he ends with a big one: social media marketing. He doesn’t say Social Media is part of the algorithm though, just that it influences readers and possible bloggers.
