Unfortunately when my business began to get scarce due to the many other ways that customers could develop and host their sites for less. I could not leverage my CF knowledge towards other types of development.
Was my CF development time worth the time and effort? NOPE! If you want to last in this business it's best to stay with the popular languages and leave the nitch languages for your hobby projects. Getting a paycheck on a regular basis is worth way more than dealing with a language you like.
