Since you want subjective view instead of facts: I see Ruby jobs all the time, though always by the same handful of companies. I see Python jobs all the time, though its always some minor sets of components/services written in it. I see Javascript jobs all the time. Hell, all those Ruby/Python companies also hire Javascript developers.
Bottom line, you can find work in any of those languages easily. Though, from my (very subjective) perspective, Ruby isn't as attractive as it once was.
