I thought that this was an interesting attempt, even if I would not subscribe to it wholeheartedly. The author takes the formal dimensions of traditional learning - objectives, time, measurement, improvement and content or knowledge - and maps them to Learning 2.0, defined loosely as a combination of social networks, collaboration, and the rest. I think that the main problem is that there isn't going to be a simply mapping like that. It's like when people ask, "how do i use blogs to teach English?" Blogs aren't a teaching tool, and you shouldn't just expect to use Web 2.0 tools to do Learning 1.0 tasks.
