Brian Lamb asks, "can DSpace be extended so that the acts of searching and interaction around these resources can themselves be learning experiences." Of course it can, but equally obviously, it doesn't. So what would it take? This is the question he explores in this post. Great whiteboard photo (should be a 'must' for every learning PowerPoint slide presentation here on in). Anyhow, to approach an answer to Brian's question: what we need for such a system to work is a social layer that exists outside walled-garden websites like Facebook and LinkedIn - a social network without the social network website. Enabled by something simple, like OpenDD.
