Sometimes it's a guest poster who writes about these things. They want the promotion and can't change the site's code.

Sometimes the site was written before whatever new standard the post is about came into being. It's a large undertaking to rewrite a whole site.

So,etimes we have to break the rules for a reason. Advocating certain standards or specs for the sake of standards, specs, or best practices is not what is important. What's important is that we know the rules and understand them well enough so that one day when we break those rules we know it's justified and we have a food reason for it. All in all, my sentiment is "use (name of spec or standard) when you can and if it makes sense".

I know you were kidding but I thought this would be a good opportunity to say this as I see a lot of standards and practices nazis out there who advocate for doing things a certain way for the sake of doing things a certain way, which is just silly.
