So it's time to bring out the guns, boxing gloves and whatever martial arts knowledge you possess. If you want the full story, start with Graeme's post here, and drill your way down from there.
I finally lost my patience with this discussion and decided that I should tell you all the truth. The final, totally objective, totally realistic answer to the question of Rails, Grails and Everything.
No, wait. I won't!
And that's it. This discussion is becoming a bit silly. I don't expect someone will see me recommending Grails, and I'm sure we all would be very surprised seeing Graeme recommend JRuby on Rails. So what's the point?
