suggest use socket.io(web socket) group people editing same content in same chanel, broadcast modification others, , notify other people , apply change. ajax not real time , costs more http://socket.io/

socket.connect(xx);  socket.on('change', function(data) {    alert('change happen!');    $scope.data = data;    $scope.$apply();  })  $scope.$watch('data', function() {    if (change) {      socket.emit('change', $scope.data);    }  })
