Web2.0 for academics!

CiteULike is basically del.icio.us for researchers. Articles are tagged and include all author information, links to related articles, links to other articles by the authors, and links to download pages. Not all of the articles listed can be downloaded for free (many of the links appear to be to Science Direct and similar sites), but most people within academic institutions have subscriptions to the services that host the articles.

 Very cool. I love to see worlds colliding.
