Dave Pollard creates his own PLE diagram (though he doesn't label it as that) and thinks about the combination of learning and social networks. With McLuhan, he describes communications tools as extensions of our senses, then observes that we want to own, rather than share, such bodily extensions. "So perhaps it is not surprising that we want the information that we get in the workplace, our way, in our own space, organized in the way it makes sense to us. We resent getting sent information (e-mail and snail mail and by telemarketers) that we did not ask for and do not want." Interestingly, he says that blogs and wikis do not serve this need well (which, I guess, is why most OLDaily readers will see this post via email or RSS feed).
