Tab your code! Readability and maintainability of code is of utmost importance.

i.e. for example, this is pretty damn hard to read:
```
{
defaults: {
section: {
block1: {
content: 'hello'
},
ad: {
image: 'boo.gif'
},
block2: {
content: 'world'
}
}
}
```

which is equivalent to:
```
{
    article: {
        section1: {
            block1: {
                content: 'hello'
            },
            ad: {
              image: 'boo.gif'
            },
            block2: {
                content: 'world'
            }
        }
    }
}
```

which is easier to read?
