Search, and Google in particular (with 90% of worldwide share), still drive vastly greater quantities of traffic than all the social networks combined (some good research from DefineMG here). Given Google’s 3.5+ Billion searches performed each day, that shouldn’t be a surprise, but to many bloggers, thinking about search, Google, and all that “SEO stuff” has been put aside in favor of Facebook shares, likes, tweets, +1s, and the more visible feedback and applause that come from social sources.
