Bill Brandon links to an article every elearning designer should read - Web 2.0 for Designers: "Enter Web 2.0, a vision of the Web in which information is broken up into “microcontent” units that can be distributed over dozens of domains. The Web of documents has morphed into a Web of data. We are no longer just looking to the same old sources for information. Now we’re looking to a new set of tools to aggregate and remix microcontent in new and useful ways."
The six items listed at the end of the article nicely sum up the new information environment we need to consider when designing learning.
