Jared,
I agree completely with your disagreement, except that I don't agree
that you should have disagreed since we actually agree. You did say
it better, though. :)
unnormalized != denormalized
(etc.)
As far as I know, structured denormalization is considered to be a
method for modification of a normalized design. There should be
disipline/method/rules that try to get the best performance increase
in a trade-off for the least collateral damage (extra coding).
I get the impression that this is standard operating procedure,
documented in industry journals, and so forth.
In your experience, what percentage of "real world" dbs are using
pure normalized designs?
Has this changed as hardware becomes more powerful and cheaper?

ps, liked the popcorn eating method, feedbags can also be found
at livestock supply places
pss, aren't you *ever* going to tell us what happened at your last
job?
