Hm. Interesting choice. Yeah I'd be curious about the reasons for that choice, too.
We have certainly had a major difficult time finding/affording CF devs.
It's funny....years ago when I decided to learn that language, I knew it was very niche and probably always would be. But there seemed to be a number of corp/gov/edu companies adopting it so I figured that I'd be able to stay working with it for years to come, exactly for that reason. So, from that standpoint it has afforded me a lot of job security, and I went into it eyes wide open and that niche bet paid off.
But I've made a concerted effort to continue to learn other skills, too, though. Job security or not, I haven't wanted to die on the CF vine.
