Jon Udell's article on Prime-Time Hypermedia highlights something that highly technical Web enthusiasts have known about (and promoted to some degree) but also can serve as an example of how a decent foundational protocol like HTTP can foster 'unanticipated benefits'.
Something that might not be obvious after reading Jon's article is that a resource-modelling viewpoint provides for a nearly infinite number of resources synthesized from one concrete media file. For example, if an intermediary provided a URI with query terms for segments of an underlying audio file, there could be an infinite number of segments - some might exist and some might not (like if they were off the end of the file). A resource is just a logical concept mapped to some concrete set of (dynamic or static) data.
