Award winning site for best use of audio. One of from a EdTech Talk Community left this message on the site when asked why they are members, "The show hosts share news, articles, new links, specific classroom resources and reference numerous forms of multimedia and feed them to the world via live webcasts. The webcasts are then saved as podcasts on the EdTechTalk site and available for download on a variety of podcast directories including itunes.
