The Internet is filled with resources one should know about, especially if you are in the field of distance education. For a nice and comprehensive list of Web 20 applications, take a look at my good friend Tom Erik Holteng`s blog.
Some links I have come across today is VSide, a 3D world calling itself the Facebook of Virtual Worlds. For those already exploring Second Life, this might be a place worth checking out. Worlds in Motion wants to build an Online World Atlas, and that might be useful for those of us who want to keep track of the various virtual worlds and online multiplayer games on the Net. For those who want an overview of Distance Education resources, the Distance-Educator.com is the place to start. Also check out the BlogTalk Radio and the eLearning Technology Talk.
