Researchers at Toshiba are working on a way of finding clusters of like-minded bloggers and others online using "social annotations." Social annotations are the tags and keywords, the comments and feedback that users, both content creators and others associate with their content. Their three-step approach could help you home in on people in a particular area of expertise much more efficiently and reliably than simply following search engine results. The same tools might also be used in targeted marketing.
