PowerPoint is widely available on most devices, but there are other ways to share your PowerPoint presentation slides, and some offer value-added features.
• SlideShare (www.SlideShare.net): This is probably the most popular slide-sharing service on the Web. You can upload multiple presentations and track who’s sharing it via embedded code, easily generated from the service. It’s also the easiest and fastest to use.
• AuthorStream (www.AuthorStream.com): AuthorStream retains all your slide animation intact, and you can share your presentation privately or publicly. You can broadcast them live, too, for meetings, training and collaboration. You can also convert your PowerPoint files to video.
• ScribD (www.ScribD.com): If your presentations are text-intensive, ScribD might be a good choice because it makes the text content of your slides searchable by users. ScribD also offers zoom, which the others don’t. It boasts more than 60 million readers a month.
