This article/opinion piece is great.
It is interested that we have indeed ended up with a web of applications that look like documents.
Not that I think this is a good idea but it would be nice to have a web of PDFs instead of what we have. Or something like a PDF that is more or less fixed. You would have to take out the scripting options from PDF so that it would not morph into a web of PDF applications.
Or maybe a web of static/JAM sites.
It would be fun to have a set of sites that do use these ideas. And have them linked. In the early days of the web I think that concept was called a "web ring." I doubt any still remembers it... :(
