As it turns out (and is obvious once you think of it), full continuations are the model for re-entrance of personalised web pages.
For example, if you are filling out a multi-page form, and at any time go back to one of the pages you already submitted, upon resubmission you effectively re-enter its continuation.
(Even if you are not into web design, this is a great example to use for teaching continuations, I think!)
P.S.: By the way, there is more than just the continuation thing in the paper, but that was what caught my fancy when reading it..
