The e-learning application, therefore, begins to look very much like a
blogging tool. It represents one node in a web of content, connected to
other nodes and content creation services used by other students. It
becomes, not an institutional or corporate application, but a personal
learning center, where content is reused and remixed according to the
student's own needs and interests. It becomes, indeed, not a single
application, but a collection of interoperating applications---an
environment rather than a system.
