An alternate voice on all this innovation...

David Snowden's presentation (17:00 min) is sensible, and provides an alternative (but not luddite) view to the prevailing "throw-caution-to-the-wind-ramming-speed!-you're-either-with-us-or-irrelevant" view of the changing education landscape. His message (part of the Future of Education online confererence 2007) is that social comuting/networks and associated web20 tools are all good and powerful, BUT they have some imporant downsides for education and societies. He also discusses briefly "nodal networks" strength over "social networks".

The first 17 minutes is his presentation, and then there's some Q/A which is also pretty good.
