The Nascent blog has a post describing a new text mining technology embedded in Nature.com's blogs that aims to give an emotional context for topics in blog posts. The purpose is to better help the site cluster blog posts together for their "stories" section. Called sentiment analysis, the technology stores metadata on each blog in the form of scores given to different terms depending upon how many positive or negative emotions are associated with it. So the phrase "Biology is awesome" gets a higher score than "I don't like glycomics." Next might be Web 2.0-enabled hand-holding or blogger group therapy.
