This one is on CMS and has a great chart comparing Web 1.0 and 2.0 components. This paragraph introduces the chart.
"If we "mash up" constructivist learning theory and the Web 2.0, we can harvest some helpful insights concerning the future of the CMS. The Web 1.0 models the traditional, unilateral publication formats. It assumes a more passive consumer of information, one who receives or buys content (such as songs, books, and weather reports) much in the way that one receives goods from a store. The Web 2.0, by contrast, with its folksonomies, bookmarking, multilateral contribution of content, and mashups, is a far more active environment. Opportunities abound for content generation, content sharing, content markup, and content repurposing. In short, the Web 2.0 models the very active engagement that is central to the learning paradigm."
