Anyway, what would you gain from asking a bunch of Ruby developers whether Ruby is "just a fad"? This is hardly the best venue for that question.
Incidentally, I didn't downvote you, just thought I'd try to explain why nobody responded to you.
Posting an inflammatory response in tandem with a question already loaded with rhetoric ("fad", "serious tool") isn't going to spur interesting or valuable debate because you've shown you're already cemented into your position before you even started.
Though I have no personal evidence for any of that ;) - I have never used Ruby, I don't know anybody in real life that does, and in fact aside from three or four mentions-in-passing I have never heard anybody even talk about it. Different worlds, I guess.
EDIT: Why am I reading a Ruby article, then? That's easy... just avoiding a bit of work. Maybe I'd find that it had done something interesting.
It read like you were just trying to make waves around the subject just for the sake of it.
