As someone who does consulting on both Ruby and .Net regularly (and appreciate both), I'd love to believe I solve 2 totally different problems (heck, that could mean I'm twice as good :-).
But no, really: I believe that apart from desktop UI-heavy applications (and I do work on this), Ruby and .Net can be used for exactly the same topics.
It feels a bit like if the headline is intended at reassuring people: you're not doing Ruby ? That's not that bad, it's ok.
My personal belief is a developer that doesn't have a grasp at both static (java/c#) and dynamic (be python or ruby or...) is really losing something there.
