"For students and lifelong adult learners, we can think of such a permanent home domain as a personal learning environment (PLE). It is not one particular cloud app, rather it is the 'pure web' with a toolset enabling the person/owner of that domain to constantly adapt it to new developments. It grows with the person over time and constantly reflects new 'interior designs' and 'remodeling' as needed. A PLE allows the owner of it to be a true author, contributor, and social interactor with the wider web ecology while still maintaining the stability of a personal home base on the web which is not dependent on the evolving marketing strategies of free portal services...
Unlike the 'exhibition model' digital portfolios, a PLE is much more naturally attuned to the authentic personal and professional needs of the owner. Of course, as in a digital portfolio, we all like to naturally exhibit/display new features. However the passive role of an 'exhibit' is only one of many features of a fluid PLE site. Along with exhibiting this or that project, a PLE might just as likely be hosting a discussion on a particular topic, asking visitors to complete a quick survey, providing a quick 'breaking news' report about storm damage in one neighborhood, contributing a 'how to' screencast video on a recently learned technique…the possibilities are endless!"
