The open education movement got a little stronger this week with the launch of Academic Earth. Run by Richard Ludlow, a new social entrepreneur only a couple of years out of Yale, Academic Earth brings video lectures from leading universities into a centralized user-friendly site. What you'll see here is an impressive early implementation of where Academic Earth plans to go. Take content-rich videos from universities, organize the videos well, make the visual experience attractive, add personal customization functionality and the ability to engage with the content, and you have a very useful service to bring to the world. I first started talking with Richard back in the fall and am really glad to see his site now ready for show time. Check it out in beta and watch it grow.
