You are coming up with a blanket judgement based on a small subset of a post (and in my opinion, not interpreting it as the poster intended). It read to me like he was talking about production usage, not tinkering. Node.js is slower and more resource intensive than Erlang (if you're comparing just async/message passing models), less productive for _most_ programmers than RoR or PHP, not as battle tested (security/stability) as Java, and fewer 3rd party libraries than most. I don't even know about the state of development tools like debuggers and profilers. My understanding is that Node.js still has stability issues (memory leaks or GC bugs?) and doesn't utilize multi-core machines very well, either. I'm all for tinkering, and I expect Node.js to be very successful and as an additional benefit to improve the V8 engine. But you're being overly sensitive to call this mild critique (albeit with a bad title) trolling.
