It's pretty amazing the kinds of tools available for free that embody web2.0. Of course, what we're seeing now is pretty much what Tim Berners-Lee had in mind when he and Robert Cailliau invented the world wide web: "a common information space in which we communicate by sharing information."
Tools like Jing allow instructors to share directions using action and audio instead of passing out paper directions. Kids can access those wherever the instructor posts them at their convenience.
Using RSS feeds from sites that have information you want to follow takes the work out of it for the user. Whenever something is added to the desired site, a message is sent to you.
Being able to share what you are doing on your screen in real time with others while communicating in chat or with a webcam using Adobe Acrobat Connect is truly amazing. Not just posting a file, but to do it live in small groups is a wonderful application of Berner-Lee's vision of the world wide web.
