Presentation Sharing-SlideShare

SlideShare allows users to share presentations via the Internet.  Your published work can be viewed by the public or you can mark it as private. You can also share your presentation via email, Facebook or Twitter.  Many non-profit organizations use SlideShare.  In fact, I noticed that The PEW Research Center has SlideShare presentations embedded into many of their published studies.  SlideShare is also a great tool for teachers and students.
