Web 2.0: A New Wave of Innovation for Teaching and Learning?

How important are blogs? Do I need Feedstar, Waypath and Daypop to search for the content in blogs? And is blogpulse truly “blogosphereic”? I had hoped that Technorati would be reigning in all these trends, but no, it’s more of the same. PubSub allows us “to literally search the future, lets students and faculty follow a search over time, perhaps across a span of weeks in a semester.” I have read too much for one day. Too many Webtastic trends for one brain that doesn’t appear to be compatibly wired. TBC
