Groovy and Grails have been around a while, and are becoming mature. There are lots of cool features and tons of great capabilities. But in the TIOBE Programming Community Index for September 2011 groovy is in the 50 to 100 ranking, which only warrants them a listing with other programs en mass that is more akin to a footnote than anything else. If you look for a job on various freelance sites, you will find the number of Groovy/Grails opportunities in the single digits, and Ruby/Rails and Python opportunities in the triple or quadruple digits. Its very hard to find low end web hosting companies that support Grails. Even Cloud Foundry from VMWare (the parent company of Spring who brought us Groovy) doesn't specifically mention it on the home page of the website
This forces the question: Is groovy worth it? Even though Groovy is fast and easy and Grails makes creating web apps efficient, I can't use it to make money (and I do have to eat). Should I stick with it, or jump ship to something else ? what do you think?
