title: What WebSockets system should I use for this?
body: <p>I'm building a Rails app where I need a real time commenting system. I'm going to use WebSockets, but I'm new to them and I'm kinda lost. I tried <code>em-websockets</code> and <code>websocket-rails</code>, but neither worked well with what I have to do. I also though of a Node.JS and Socket.io app, but I don't know how to start with that.</p>
  
  <p>What I want to do is send a WebSocket message when a new comment is made on a post, on the <code>create</code> action of my CommentsController. I'll send a message containing the comment content and creator and the post ID.</p>
  
  <p>Thanks in advance! :D</p>
