I don't think job sites are really the best metric for Rails jobs - in my experience no one bothers posting them there because the people who know Rails well aren't trawling job sites for work. When I was looking for a new job recently I was mostly looking at places like Stack Overflow jobs, along with the London Ruby User Group mailing list which tends to get three or four job postings a week - I haven't looked at a mainstream job site since about 2008. If you want a better sense of how much work there is add a few years of Rails experience to a Linked In profile and watch the recruiters start circling.
