I'm using it in production in multiple places, and I adore it. I will never go back. If you want to just dip your toes in, look at SCSS. It's a superset of CSS, so you can take your existing stylesheets and start using more advanced features. That said, I prefer pure SASS. It's cleaner, IMO, forces better organization, and is less typing.
