I'm sure you sometimes click on hyperlinks besides those that show up in search results. The point is to make navigation of that manner via related hyper-links better, which is somewhat orthogonal to search we think. Sure, you can search and find anything, but it's not quite the same as just browsing by clicking links.

Google uses the link graph to find stuff related to the keyword. You're proposing to have users do it, right?

I'm proposing to have users create a new link-graph, separate from the web's own inherent link graph. Keywords have nothing to do with it. :) - Looks like my home page isn't as clear as I thought.
