I am amazed by how much Olympic related content is being uploaded to SlideShare. There are slideshows about the food, about the cheerleader, the opening ceremony. Its a very different feel than the video coverage. Slideshows can give you an broad view of a topic with images and text, whereas video is often about a specific incident, a locale.
