Been through it before, when I used ColdFusion. Not highly regarded these days, but among the options at the time, it was ridiculously fast to build applications in. To this day, even has some features missing in other languages/frameworks. However, things shift in the industry. In CF's case, it was the shift to open source and package managers, IMO. There's no value in casting stones at the use cases that undermine your worldview. (Personally I love Ruby, but if and when the time comes, I'll move on to whatever meets the needs of my employer/client)
