Twine

I just read about a new social network called Twine. Read more at Nicholas Carr's blog

"What makes Twine interesting is its Semantic Web underpinnings. (Spivack likes to throw around terms like “extensible ontologies.”) Rich with cross-referenced meta-data, the site’s underlying database allows Twine to interpret the information you put into it, automatically categorizing data, applying a set of relevant tags, following links to pull in related information, and so on. Its aim is to provide each member, or group of members, with a dedicated virtual librarian, working behind the scenes to organize a diverse or even chaotic array of information into a useful, structured form."
