I actually worked with CF most of my career, spoke at some CF conferences, and still run the Houston CF user group. Don't use it as much as I used to (moved mostly to Rails for the ecosystem), but it's still a very capable language.
I've built production apps in Rails, PHP, and CF, and I've tinkered with Go, Python, etc. I still haven't found a language that gets interns from "don't know HTML" to "working dynamic web thing" faster than ColdFusion.
