I don't use Ruby on Rails but if you just scan open tech positions you'll see a lot of new startups and existing companies are based on Ruby. So I'd say it is not dying, but likely has slowed down some.

IMO every language essentially goes through this, gets popular for some period and then slows down to become either mainstream or it falls away. I'd personally say Ruby went mainstream, it definitely isn't fringe and it isn't the new hot stuff but real companies rely on it daily.
