Well, I have it, and there's a couple of it at the company I work at too.

Has it made you a better coder?

I wouldn't necessarily say that in my case, but it's certainly made some of my guys better programmers, and their code is now easier to maintain!

Does the ideas presented in the book help in any way with other languages you know (ASP, CFM, JavaScript, etc)?

Yes. I'd say more than half of the ideas in the book are suitable for other languages.

You should definitely get that book :-)
