I have experience with Python and Twisted. For many types of applications such as realtime web collaboration, the Node stack is not only much easier to use but performs better.
If you like Python then take a look at ToffeeScript. It is cleaner than Python and works with Node.
The Node package management system is based on semantic versioning and combined with the dependency management and massive 54000 module easily searchable ecosystem is much more useful than Python.
You really don't know what you are talking about and you are pissing me off with your offhanded winky smug dismissal of Node and Node programmers.
I have been coding for more than 20 years using many different languages and platforms from c/c++ to ocaml to python to c#. And Node.js with ToffeeScript and npm is just a more advanced way to do development compared to any of those for most types of applications.
Build a few projects using Node.js and ToffeeScript and modules from npm and then come back and we will compare the experience to building the equivalent with Python/Twisted or Go.
By the way I like Go for some things but its not the best new language for systems development. I think Rust and nimrod have Go beat.
