Live Binders is a new (beta) site I first read about on Richard Byrne's blog. This is very similar to Toobla, in that it is designed to help organize your digital content. LB is ideal for education because it organizes the content in one easily visualized place, or straight from their site, "Teachers place livebinders on desktops so kids don’t have to type addresses or get lost searching on the web. And they don't have to add a bookmark to every computer everytime they have a new link to share - they can just update the livebinder."
I can see this being used by teachers/students to create one location to share their content: web pages, slide shows, links, etc. I like to think of it as the ultimate PDF because it is 100% interactive. For example, a page of links, would instead be a binder of web pages (where all the links are live), etc etc.
