Embracing Best Practice

While the language makes me cringe (current employer is all about that best-whatever crap, they've bought the business consultant lingo but not the underlying ideas), but I think this is moving in the right direction. I'd like to see less pontificating about standards and more presenting of new practices, with pros and cons, leaving the determination of what is best for a given project up to the end user. Also, rambling about how it's all a balancing act doesn't do it for me either. I want to hear a strong case for a given solution. I know that there is rarely one standard solution that will work everywhere. Give me an argument for your way, and if you're really good you'll discuss both sides.
