Yup. I disagree with my previous self all the time. Since I see the same
characteristic in just about everybody, I can only conclude that we all would
benefit from toning down the vociferousness with which we propound our
dogma. As my father was fond of saying: "The best way to handle a vicious
dogma is with a big stigma." :-).
My friend Ken Auer has always been suspicious of The Methodologists.
I've heard him accuse them more than once of having nice theories that
obviously were never tested against real life, practical problems.
Anyway, I hope to see you again at the Squeak BOF in Denver (OOPSLA '99).
We can discuss this at length over a cup of coffee...
