The title of this post is slightly tongue-in-cheek because I have my doubts about whether there is such a thing as PLEs that are distinct from existing software product categories. If there were, then after years of people talking about them, one would think there would have been an example by now that everybody could point to and say, “Yes, we all agree that is a Personal Learning Environment and not a Learning Management System, a Virtual Learning Environment, an ePortfolio, an RSS reader, a personal portal, or whatever.” Then again, maybe the PLE is an idea whose time has finally come. I believe that learning environment developers are embracing many of the articulated values behind the PLE and experimenting with different ways to embody those values. Xplana.com, which launched this week, is one example.
