There have been recently a few posts about new tools for learning online, with videos or just with some books. As it seems, the learning goes Open-Source and I have to say that I really appreciate this.
The most recent example of E-Learning is Academic Earth. An initiative coming from the United States as many innovative things come from there. The site is reachable under Academicearth.org. The student or interested person will find there whole lectures and courses on video in good quality, as the example down below shows. There must have been also some effort to cut all these videos, in a way, that the slideshows of the lecturer are shown in the right moment.
What I think is really remarkable about Academic Earth, is the fact that the founders Richard Ludlow (graduated at Yale) and Chris Bruner (graduated at Stanford) have built in from the beginning the networking tools a modern student uses today. You can embed the videos easily (as you see above), can share them on different platforms such as Facebook, Del.icio.us... There are many things more, like downloading a movie, mail a link, rate it and so on. This is really something great.
