Usually what @curie does is when they find a post of this quality, they upvote it! You can see among the upvoters there is curie and @hendrikdegrote. They are @curie upvotes, which means they noticed and have rewarded you!

After upvoting, they may or may not feature you in their showcase post. In this case, i think they have as yet only upvoted you! Which is all the same well! Congrats again.
