The impact of the social conversations has dramatically increased. More than 133 million blogs have been indexed since 2002. Twitter has doubled in size this year alone to roughly 30 million users, who create 1,500 new "Tweets" every second. Facebook's 35-year-old-plus demographic grew to 12 million users in the first quarter of 2009. But that's only part of the story. The results from search engines are even more important. 2,300 searches are performed every second of every day.
