Don't worry about it, I got used to occasional trolling on HN. Basically if you are not talking about the newest hottest community approved thing or you have a slightly different opinion than the HN standard you get down voted. Making which programming language is the best for web applications sound like "node.js is the silver bullet of web apps, it also cures cancer and aids at the same time" is laughable. I enlisted several technical details why Java (besides Erlang and Go) is the best for scalable web applications while the other guy was just "java sucks node.js rocks". If I get down voted, it tells more about the people reading this site than anything else.
