Video killed the text-based star

Christina Wodtke over at Elegant Hack pointed me to Jon Udell's screencast "Heavy metal umlaut: the movie" in which he tracks the development of Wikipedia's Heavy metal umlaut page. While the content of the screencast is fascinating enough, it's Udell's combined use of Wikipedia's page edit history and screen capture software to create a captivating instructional video that really got me thinking, "This is the future of online education in writing."
