Demo of push is broken
Steps to re-produce:
1. In Firefox
2. Scroll down to the near bottom of http://maker.github.io/ratchet/
3. Click the "Go to page 2" item in the demo window

It shows this error in the web console.

```
[19:56:37.400] TypeError: Value not an object. @ http://maker.github.io/ratchet/js/fingerblast.js:27
--
[19:58:36.703] TypeError: data.title.innerText is undefined @ http://maker.github.io/ratchet/dist/ratchet.js:494
```

And it goes to http://maker.github.io/ratchet/undefined
