       | Internet. Englebart and the Augment Project at SRI made some of
       | the vision real.

       | Will definitely be watching this!

       | As I understand it Nelson's vision is still not grasped today.
       | 
       | His original hyperlink was _bi-directional_.
       | 
       | Pause and think about that for a moment.
       | 
       | In practice, at the time, the target in a client-server
       | implementation had no way to store "return" links pointing to it.
       | The WWW could not rise to Nelson's ambition. Maybe that's changed
       | today, and we could certainly rewrite servers or create a more
       | peer-oriented way of going about things.
       | 
       | The upshot is a totally changed "Web", in which search is
       | fundamentally different from a centralised index a-la Google.

         | Not sure I understand. Can you explain? How would a
         | bidirectional link work? What would be an example? And how
         | would that free us from the need for centralized search
         | engines, for example? I ask not because I doubt, but because I
         | have a hunch that you may be right. Thanks!

           | I suppose there's three things to talk about. Ted Nelson. The
           | idea. Possible implementation.
           | 
           | First, Ted.
           | 
           | He's clearly a genius, also the type who has a lot of magical
           | thinking. Which I mean that in a mostly good way.
           | 
           | Then there's the theory. Graph theory. The WWW (basic
           | concept) is an ephemeral directed graph under asymmetrical
           | navigation, such that sources are initiated by clients
           | (requests) to destinations on listening servers
           | (respondents). It's a stateless static document model, and
           | within a document the outdegree is the (known) number of
           | links in a document, and the indegree is the (unknown) number
           | of all other links in documents out there that point to it.
           | Links are just text strings (URLS).
           | 
           | As it stands the only way to know the indegree is to spider
           | all documents exhaustively and count. Larry Page's "rank" did
           | this, giving a rough metric of how "important" a document was
           | by its popularity (indegree), which launched Google.
           | 
           | As I understood it, Ted wanted links that were containers of
           | other links that referred to them. The server would somehow
           | need to watch for these coming in, and remember them. The
           | upshot is a much richer information space.
           | 
           | Implementation. Can-o-worms. What happens if a million pages
           | refer to yours? How to prune dead return links? How to trust
           | servers to be honest? It's completely different
           | privacy/visibility universe.
           | 
           | So I think it's just a theoretical pipe dream.
           | 
           | But I hope I may be proved wrong by really smart people. I
           | think the key is to move away from client-server to something
           | a bit more flattened, perhaps with IPFS or suchlike
           | underneath. Who knows.
