Web 2.0 and New Learning Paradigms

the Net as the platform, or the multi-device oriented system, changes the concept of studying at any place, any time; collective intelligence and rich user experiences affects the concept of authority in educational systems; tags and RSS readers allow us to revisit traditional taxonomy, knowledge organization and information retrieval; the option to choose between several devices to work on learning tasks (PDA, iPod, computer...) seems to be a technical and not relevant question, but that implies the option to learn at every time: while travelling, walking, etc. In Web 2.0, the difference between study times and other times seems to disappear.
