Shakespeare, an early evangelist of the World Wide Web, wrote in Othello: "There is magic in the web".
The web truly is magic, with books that connect to other books and documents and so on and the whole library is connected.
The magic stems from a magic incantation: the hyperlink. Authors can, without much effort, write, invisibly, around any text, "when clicked upon, open such-and-such a document". As a result, anything the author feels is important can be linked to anything the author thinks is relevant, such as the definitions or entries in Wikipedia.
Instead of just special hyperlinks, why not make all words hyperwords?
This way you could look up any words in the dictionary (or Wikipedia entry, or glossary entry). You could perform searches on any text and you could blog about sections in a single paragraph and email text with a click, copy text with the address of where it came from copied as well. You could translate words, look addresses up on maps, search for people and see if you know anyone who knows them.
You get the freedom to explore, to follow any connections you want, you become free to navigate the magic of the web through the magic of every single word within it.
