I say - with differing commentary after the first 4-5 sentences - in every class I teach:
"I don't like the phrase 'best practice'. I won't use it. It's presumptuous and condescending. What's best for me might suck for you. Who am I to know your business requirements? There is only one true 'best practice', in my view, and that is simply to have practices that you and your team follow that serve to further your business goals and meet your business requirements. SharePoint isn't a best practice, but a system to support a corporate culture of collaboration or information sharing is a practice that many businesses can agree with. jQuery isn't a best practice, but using a framework that improves your team's productivity and helps it to meet your business' requirements - that's a good practice to follow."
We need a new phrase that gets the point across without the cognitive burden of being condescending and presumptuous. Consensus practice? Common practice? Popular practice? I don't know. But I know that "best" is a superlative that is too often used to disguise a marketing goal or to dazzle the listener/reader into accepting the superiority of the person using it.
