I'm not really a TED fan, but it's David Wiley, so I'll definitely pass the link along. Wesley Fryer summarizes, "David argues, 'The most successful educators share most thoroughly with the most students.' For him, education is DEFINED as a relationship of sharing. Does this make you reconsider whether or not YOU should be blogging regularly? What about CLOSED, "walled-garden" learning management systems? Still think Moodle is "the bomb" just because it's open source? Think again. Education IS sharing, and the more generously we share, the better we educate others as well as ourselves. Very important and powerful ideas here."
