"*could* care less"?!

Doesn't matter.  The same is true of the web, but it doesn't stop
google, does it?  It just ignores the dead ends and follows what links
it can.  Remember, it just takes _one_ good link into a "sparsely
populated island" and it's on the mainland.  That's the magic of
distributed systems like the web (and F&N) -- there's no one point of
failure.

And there's even better news --

Fantastic.  So LC's and Index Data's server can both have huge F&N
lists and will provide either (A) great start points for google-like
spiders, or (B) wonderful fan-outs when spiders that start elsewhere
happen to stumble across them.

What could be better?

If history has taught us anything, surely it's that a vague, ill
disciplined, unstructured, decentralised mess like the web has far,
far higher survival potential than something "better".  F&N is the
way!  Let's do it!

(Jaded observers might feel that today I am full of random, unfocussed
energy in search of something to be enthusiastic about.  There may be
some truth in that.  Still, this is a good plan.)
