...which happens to cover 90% of the space on a doc-oriented Web. That
people use.
(A lot of of people also use Yahoo! etc, but Google is the poster child)

Nah, just the bits you're interested in. Delegate the number crunching.

Wow, fighting talk. I think the originally-Ancona guys are going to
have to build this.

What I want someone to find for me is a little algorighm in which you
got a bunch of nodes, they shoot out creepy tendrils. When a tendril
from one creepy thing meets another, all hell breaks loose (but
otherrwise dull & rainsome). That seems to be were we are.

That was almost Biblical, shame is I agree.

Ditto.
