I have started using SlideShare to give all my talks. Why? I don't like PowerPoint as a live presentation tool. Second, I refer to lots of websites in my presentations and hate having to switch between Full Screen and web browser. I always loose my place in the presentation and then have to start from the beginning. SlideShare handles this much more elegantly.
There are a few tricks to using SlideShare for a live presentation.
-Sometimes the images don't render very well (especially for a live presentation). You can make the rendering much better by saving as pdf (and unchecking option for compressing while exporting to pdf).
-Second, SlideShare can sometimes be slow and its annoying waiting for the screen to load up in front of an audience. Easy solution is to cache the whole presentation beforehand. I go through the whole presentation in full screen mode - so during the live talk, it goes all smoothly.
-Going back and forth with the web. This is the part I like the most. When you are in full screen mode, you can press "Esc" at any time. I already have the websites open that I want to show. When I am done with it, I put SlideShare into full screen mode again. It starts at the right point.
The best part is since everyone in the audience has seen me using SlideShare, they know where to go to get the slides. Ever since I started doing this, I get a lot more traffic to my slides and a many more talk invitations!
Anyone else using SlideShare for live presentations?
