Andy Carvin has a nice article about social bookmarking in general, and del.icio.us in particular, with promises of further articles about how social bookmarking can be used in education. Let's hope he branches out beyond del.icio.us to places like Penn Tags and H20. The geek set has for years now been praising the virtues of social bookmarking. Now it's time to start documenting the actual uses, and looking more closely at just how this practice might make a difference. Anyone have a story to tell?
