I think the only (briefly) successful metaweb service I used was a &quot;passive&quot; Roleplaying Game. It ran in the background while you surfed and you could leave comments, bombs, treasures, etc on websites you visited. I would forget it was running, visit an interesting article, and BOOM a bomb would go off taking my hit points. It was called aethernet or ethernet or something like that. I can&#x27;t find any evidence of its existence anywhere online now.<p>It also had a central repository of links and users would build &quot;adventures&quot; that were lists of links and you would visit each site along the narrative gaining experience and running into traps laid by other players when you wanted to be active.<p>I would love to have a layer of academic discourse over anything online, but I agree it seems unlikely this would take off considering how large the world wide web is and how spread out those comments would be.
