Ray Tolley (http://efoliointheuk.blogspot.com/) got me thinking.
If you are going to use the term eportfolio in a particular, restricted way, then you need to define the term precisely. Many people have several eportfolios: LinkedIn, Facebook, Flickr, blogs, PebblePad, various forums and repositories, their own web site, a Monster.com CV, etc. Many more people have none. Those with several often cross reference between them. We may choose to call just one of these collections our portfolio. But, if we do, we should say why this one, not that one. And, given the fast-moving field, we must be tolerant of exceptions to any rule and be willing to negotiate meaning.
