This is the article I'm going to refer people to to explain the problems that I have with nodejs. All of these (absolutely true) observations aside, I really like how the the nodejs trend has brought concurrent async-style thinking into the mainstream of web programming.

By "all of these observations aside," I mean that I hate working with it personally, and I'll be using Erlang/Webmachine thank you, but I learn new ways to think about modern problems every day from many of the great people that are part of the nodejs juggernaut.
