The barrier to the personal learning environment (PLE) is not technological, argues James Farmer. "Major institutions aren't going to start switching their LMSs to our PLEs any time soon and yes security, ip, maturity and (above all IMO) the structuralist transmissive models that LMSs on the whole play up to and re-enforce make this a difficult journey." Still, "stranger things have happened." Farmer suggests that personal aggregation will play a key role (and I agree) and that the blog (such as offered by WordPress) forms the basis of this environment. I'm not as inclined to say "easy peasy" as Farmer, but my view of the structure of the PLE is similar to his. See also Marc Sheffner on this item.
