This afternoon I came across a website devoted to listing the best of web 2.0 for education. Web 2.0 teaching tools offers a blog with updates about the best 2.0 teaching and learning tools, as well as links to individual tool websites. You'll definitely want to check it out if you're an online teacher (see how useful and fun it is to add interactive tools like del.icio.us to your virtual curriculum). If you're an online student, you may be able to use some of these tools for working on group projects or studying with other class members.
