Yes, the hype machine got into full gear a few years ago and tried to say Node was the answer to everything. But that happens with every technology that gets big. Node does solve a certain class of problems, namely streaming blocking IO, very very well. Things that would have taken hundreds of lines of C code can be turned into 10 lines of Node. For a certain class of problems is really is a silver bullet. Just don't try to shoot things that aren't blocking io werewolves.
