When we think of e-learning these days, we tend to think of learning management systems, enterprise systems, and integrated courseware. Large, complex, do-everything pieces. But when we look at the internet technologies that have actually been successful - things like email, web sites, and blogs - we find that what works is exactly the opposite: small pieces, loosely joined. This lecture looks at what's wrong with enterprise e-learning and why the small pieces approach will work better, and will describe recent and innovative work using such technology, including the use of blogs, wikis, and RSS.
