JavaScript Developer Survey 2011

There's also the .NET JScript interpreter.

I don't think his beef has to do with server vs. client side scripting. Rather, its strange that you compare Node (a set of libraries that augment and enhance v8 -- the actual interpreter), to Rhino (an actual interpreter written on top of the jvm). Its kind of like asking "do you prefer to write asynchronous apps, or run on the jvm?" (two orthogonal issues). The way the question is worded now it seems like its just asking "so is everyone just using node.js or what?".

If you actually want to ask which server side interpreter people prefer, the list should look more like []v8 []jsc, []rhino, []ironjs, etc. (and not include node). Ask this question if you want to know things like "which implementation of js do you feel more complete", "which interpreter has the best memory characteristics", etc.

If you then separately want to ask what "platform" people are using, then it would be []node.js, []whatever else there is out there. Ask this question if you want to know things like "what methodologies do you prefer for your server apps".
