Dry aging doesn't work well with all cuts of meat, in my experience, so maybe that was the problem in that old post back in 2009. Some cuts work very well indeed. Beef jerky using a dehydrator is very similar to dry aging and I now tend to make my jerky by just dry aging (air drying) it, which produces better tasting jerky than machine-dried jerky. The best steak restaurants dry-age their steaks, and they wouldn't be able to sell them if they tasted nasty.
I believe there was a thread some time ago on some American butcher and specialty shops and restaurants that make traditional raw fermented sausage and age some of their meats. Unfortunately, the USDA has been making things more and more difficult for them.
