The Web 2.0 is providing new ways to create content, collaborate, and participate in wide-reaching discussions. For a graduate course in building such interactive services, I have used these recent technological advances to give students exposure to what they are to design. I will briefly describe some technologies that I have used from Web 2.0 type of applications. The first is Twitter which I use to carry classroom discussions outside of email and outside of classroom boundaries (physical and electronic). I also use DropBox as a way to share documents with students in groups. I have also used podcasts, Google Docs, Google Calendar, SlideShare, CiteULike, Delicious, and LinkedIn for other purposes related to my teaching/research.
