I use Ruby a lot for small database tasks (love ActiveRecord!) and for using Rails for some web applications (not with scaffolding, mostly generating controllers and writing my own code).
That said, for a lot of what I do, Ruby is much more than an order of magnitude slower that compiled Common Lisp. I find myself still using Ruby and Java when appropriate, but for most tasks, I am going back to using Common Lisp. Better language, and the learning curve is not so bad (I have been using Lisp for over 25 years, and I am already up to a 'moderate' level of competence :-)
