Blogging is not a technology. It's a social practice. Using blogging software is trivial compared with the social and cultural understandings that are necessary to do it effectively.I was listening to a talk by British blogger/teacher Peter Ford recently. He was saying something similar: that the technology has now become so simple we don't need to teach it; that it's not about the technology, it's about using tools that help me be a better teacher; the tools Peter introduces are tools that help teachers do what they 've been doing for years, namely have students read, write, think and communicate.
Alan November said something similar at the eLive! conference in Edinburgh a few weeks ago.
