I have been getting requests to update the Joel Test since the day it appeared.
Remember what it's for -- it's a sloppy, irresponsible test. Questions are on the Joel Test because you can get quick thumbs up or thumbs down answers. Even recruiters at high tech firms know the answers. Most companies are either firmly in the 0-4 camp or firmly in the 9-12 camp.
It's a good way to judge quickly how professional a development organization is. It is not a catalog of good practices, nor an up-to-date bible for professional software development. It's a list of things you can reasonably find out during a one hour interview to decide if the company you're thinking of working at is a seat of the pants, 0-4 chop shop, or a striving, professional 9-12 company that cares about doing good development work.
Of course, if I wrote the article today, the stories and the explanations might be different. But I can't in good faith say that a company that is still using svn instead of git is necessarily doing it wrong. They might be missing out on some awesome DVCS goodness, but at least they're not emailing each other source code files! And I agree that continuous integration is a sweet idea, but honestly, what I'm really trying to protect you from is the company that goes for weeks at a time without gathering everyone's code in one place and building it.
There have been huge changes in the way software is developed in the last decade. You used to worry about importing files from your competitor's format. Now you worry about virally spreading your social network activities through Facebook and Twitter. A 19" monitor used to be sweet. Now you expect 30" monitors and SSDs. But the 12 points still apply for deciding if a company is going to be a reasonably professional place to work or a hack shop.
