It is important that you memorize your Web presentation, rather than relying on note cards. Just as the audience will use your PowerPoint slides as a tool, you can also utilize them to remember what information you wish to speak about next. However, do not read directly from your slides or clutter them with information just so that you won't have to memorize anything. Reading directly from notes can make you sound mechanical and affect the flow of your speech. You should know your Web presentation inside and out before you step in front of an audience.
