Strange, considering there are always Rails jobs on craigslist in every major city and on all startup boards. Hell, I don't even actively seek out contract work and have offers on a weekly basis (in person, not even counting online) from people looking for Ruby/Python web development.
PHP, ASP.net or some of the many Java frameworks...
So? You put stock in argumentum ad populum? Hell, why not rip on Django while you're at it, considering there are far fewer Django jobs than Rails jobs? Nevermind the fact that despite Python and Ruby web frameworks being less widely used than PHP overall they are still very strongly represented among the most successful and innovative web projects of the past decade.
