I'm a Pythonista that loves JavaScript and thinks Node.js is a waste of effort on the part of humanity.
I'm mostly ambivalent. Node, to me, feels like an attempt to bring twisted to server side JS.
How much have you used it?
I fear that few programmers understand the perspectives brought by Node and JS.
Node.js didn't bring anything new to the table. We've had event loops and non-blocking code for almost half a century.
Don't lump JS into this.
Hyperbolic much?
That's an unfair presumption. That's just a coming from a few twitter users and it doesn't really represent the whole rubyist community.
I've found the whole rubyist community to be somewhat hateful towards any other languages. It makes it hard to want to use the language when the suggestions I get on my "gems" are "that's not ruby-enough of a name" or "You need to break out of your python mode, your name isn't clever enough" :P
