MLX Item #278 There has been a lot of discussion of the use of RSS and Trackback in relation to the sharing of "learning objects." A very interesting concept... The sharing of resources becomes a lot easier with the use of this kind of technology.
Speaking of Trackback, The O'Reilly Emerging Technologies Conference is also doing something interesting with Trackback. Each of the session descriptions has a Trackback url. Those at the conference blogging the session can point to the url and those looking for further information can easily see all the posts associated with that session.
