// assumes you add a timestamp field to each record (see Firebase.ServerValue.TIMESTAMP)
// pros: fast and done server-side (less bandwidth, faster response), simple
// cons: a few bytes on each record for the timestamp
var ref = new Firebase(...);
ref.orderByChild('timestamp').startAt(Date.now()).on('child_added', function(snapshot) {
  console.log('new record', snap.key());
});

This example shows how you can use your data structure as a basis for 
your Firebase security rules to implement role-based security. We store
each user by their Twitter uid, and use the following simplistic approach
for user roles:

0 - GUEST
10 - USER
20 - MODERATOR
