If we have to talk about PLE (Personal Learning Environments) (blech. why does every damned thing need a name and/or acronym?), can we at least not define it to death?
"PLE" is a verb, not a noun.
"PLE" is something you do, not something you have. It's an action, not a thing. It's a way of interacting with others, not a way of "getting personalized learning."
You can't go out and set up your PLE. You are part of your PLE. You have it already. You can't seek to personalize your learning - if your learning isn't already personalized, you're not learning.
