[Air-L] social technology or social media

Hi everyone, Some interesting discussions on the internet and homelessness proved another good example of social technology. I am interested in any theoretical background readings or frameworks in studing this field. I also want to have some examplary cases of social technologies other than Wikipedia, MySpace, Blogs, and Facebook. Do you have any specific area that Web 2.0 changes? If you let me share your ideas, it will be appreciated. Jin School of Communication Simon Fraser University
