I don't know what is the best type of Exception here? Maybe like that?
```java
thrown new NoSuchElementException("Did you remember to put your facebook APP_ID and Secret in mamute.properties?");
```

Or create a new exception here?
```java
thrown new SocialPropertyNotFoundException("Did you remember to put.... ?");
```
