Since SlideRocket is web-based you don't have to worry about using up your hard drive space or filling up a home directory on the server. Creations can be stored and shared from centralized libraries where everything can be searched, tagged, and sorted. Imported personal images, flash animations, and video can be stored in the Assets section. Video from Flickr, TeacherTube and other sites can easily be imported. Its plug-in architecture allows for an endless number of slide transitions and effects, 2-D and 3-D, that will work on a PC, Mac, or Linux.
Sharing your work with everyone is as easy as publishing the URL or embedding it into your webpage. You can control who sees your creation by only inviting certain people. Once shared, either to a few or many, you have control and can see when it was viewed and by whom, and how long they spent on each slide. Any Google spreadsheet can be imported and then it becomes a fully styleable table or chart. There are shapes and drawing tools to make annotations or diagrams. Hyperlinking to any element is a breeze.
SlideRocket is another solution to help make presentations look great and add a little more "attitude." As Nick Yingling says, "Sometimes its not always what you're saying so much as how you're saying it."
