You were not downvoted because people took your comment literally, you were downvoted because being snarky runs against the Hacker News guidelines, specifically:

> Be civil. Don't say things you wouldn't say face-to-face. Don't be snarky. Comments should get more civil and substantive, not less, as a topic gets more divisive.

Sometimes snarky comments will be forgiven if they are substantive. Yours contributes very little beyond what the parent/grandparent comments had already mentioned.

Thank you for the quick heads up! I’ll make sure to familiarize myself with said guidelines. It’s very useful!
