If the rules were in some particular order, this would have received much higher ranking.
Simple Rule 15: The Bat Rule:
Ping, then listen. Or fail.
Because bats, you know, use echolocation: ping! and detect food and obstacles by the signal that bounces back. A bat that doesn’t ping doesn’t eat, but neither does a bat that doesn’t listen.
Your ping is a question. You have to ping. If you don’t ask any questions, you don’t get any information. But if you ping and then immediately start thinking about your next ping instead of listening to the signal that comes back to you, why ping at all?
You don’t get any information by asking questions. Ping, then listen. Or fail.
