I think that individual code design culture comes from trying many languages and different use cases, picking up the best practices on the way. I remember using Pascal and then acknowledging that "begin" and "end" are better expressed with curly braces in C. When using Delphi I learnt a lot of OOP principles so I could later easily pickup Java and took some good habits from there also, later came PHP where I started noticing vertical readability is important, so when I saw Python I was stunned. Functional programming hit me, but not so hard, because I used AutoCAD LISP years ago and it felt natural. Trough the years I started to notice new things I would need in my daily coding and I found nirvana when I saw Ruby.

After years of coding one develops their coding personality that they're happy with and I think their code has just a right mix of carelessness and precision which could be never learned from a script kiddie book.
