Martin Weller’s blog, The Ed Techie, was the first technology blog that I followed and he’s a constant stream of intrestingness. His latest post is really valuable for anyone interested in ed-tech generally, but also open educational models specifically. He has done interviews with a number of OU luminaries (Martin Bean, Grainne Conole, Andrew Law and Simon Buckinham-Shum) on the questions of the benefits of technology for learning and interesting issues around openness.
