If you're so smart, how come you ain't rich?
Just recalled Philip’s comment when I was reading Martin Fowler’s Analysis Patterns: “Don’t take advice from someone who says you should program your applications in Smalltalk!”
Guess he has a point. It’s at least worth to work with a discount factor: If someone tries to tell you how you should develop software, look at the software he’s built himself. Is that the kind of software you dream of building? Is it great software?
If not, he may still have valid points, but factor in a discount factor of .2 or so.
