+      - The 'random_choice' feature can be used to pick something at random. While it's not a load balancer (there are modules for those),
+        it can somewhat be used as a poor man's load balancer in a MacGyver like situation.
+      - At a more basic level, they can be used to add chaos and excitement to otherwise predictable automation environments.
