title: Value from client.get() is "true" instead of the real value
body: <p>I am using nowjs and node_redis. I am trying to create something very simple. But so far, the tutorial have left me blank because they only do console.log().</p>
  
  <pre><code>//REDIS
  var redis = require("redis"),
      client = redis.createClient();
  
  client.on("error", function (err) {
      console.log("Error "+ err);
  });
  
  client.set("card", "apple");
  
  everyone.now.signalShowRedisCard = function() {
      nowjs.getGroup(this.now.room).now.receiveShowRedisCard(client.get("card").toString());
  }
  </code></pre>
  
  <p>In my client side:</p>
  
  <pre><code>now.receiveShowRedisCard = function(card_id) {
      alert("redis card: "+card_id);
  }
  </code></pre>
  
  <p>The alert only gives out "true" - I was expecting to get the value of the key "card" which is "apple".</p>
  
  <p>Any ideas?</p>
