Man, Grails / Groovy never get any love from these poll authors! C'mon, Grails rocks people... :-)<p>Seriously, I switched all of our development from Java/Tapestry/etc. to Groovy/Grails a few years ago, and really couldn't be happier with the decision. Grails isn't flawless, but it mostly "just works" and makes my life SO much easier than before.<p>No, it isn't the "flavor of the day" like node.js or what-have-you, but it works, it stays out of the way, and gets the job done. And it lets me leverage the decade plus of experience doing Java that I previously experienced. What more could you ask for?
