I had the pleasure of missing Ted's original post. I read it before this one, and it was pretty misinformed. I could write a similar article arguing that assembly is useless because it takes so much code to implement a web server using it.

If your server runs in a single thread AND you do expensive calculations per request, you're doing it wrong. You should be caching results, and you need to either move the processing work to a backend server (written in C or something) or shard the frontend across a lot of cores (multiple processes / webworkers). In any of these configurations, nodejs will work great on the front end.

But, most of Ted's post was needless bile. The argument he made isn't justified by the evidence he gave. Don't bother trying to argue with him, its not worth your time.
