Actually, Kai's suggestion of the thread score thingy in
gnus-summary-line-format got me thinking. Looking at how it is
defined, I tried

(setq gnus-summary-highlight
  '(((> (gnus-thread-total-score (and (boundp 'thread) (car thread)))
        3000)
      . italic)))

[Excuse lousy formatting]

It seems to work... (that particular example makes everything with a
cumulative thread score >3000 italic).

But I have to admit, I would have no idea how to generalise or explain
this. Where did the variable "thread" come from? When is it valid? How
can I get something similar form myself to pass to
gnus-thread-total-score, should I wish?

There comes a point where "use the source" as a mantra becomes more a
hindrance than a help. I do wish that some of this sort of thing were
better documented (I'm not enough of a Lisp coder to be able to
understand and document it). Or at least that there were more web
resources - my.gnus.org doesn't seem to get updated very frequently,
and I know of no other significant sites...
