Most people who use the phrase “Best Practices” probably don’t know what they are. I haven’t really found anyone using these terms who can explain why these practices are truly “best”, and in the realm of software engineering (not so much for web dev.), the code of people who endorse them tends to be awful. They can sometimes spit out why one model is better than another particular model, because they’ve memorized the dogma, but present them with a completely new paradigm and ask them to compare it and they cannot. It seems like they’re substituting process for talent.
