Amazon just announced that authors can upload video to their Amazon Author Page.
"Your video will display on the Author Page after uploading and approving it on the new Video tab in Author Central.
"Why Video? Video is a rich way to provide customers with information about an author and their books, and is in-line with our efforts to make authors more visible to Amazon customers. Many of you have also asked for video via our feedback form.
"Video will display under your profile photo, biography and “related authors” links. A sample video from writer Maria Murnane is already uploaded and live on the Maria Murnane Author Page:"
