I'm wondering.
I noticed, for the first time, this diamond at the end of one person's comment on a BD box (not mine) 💎
I don't recall ever seeing a diamond at the end of someone's comment on a box.
I looked at other boxes with BDs, none of the comments have the diamond.

'sup wit dat?

Is it something the commenter did?

Is it something the commenter did?

Yep. *nodding* Just like you did it in that post. =)

I didn't anything more than copy the comment and paste it into my question.
I guess they thought their comment required a BD comment on a BD box.

From the AQ Glossary...
Blue Diamond
An often controversial concept where AQ attempts to mark some of the best letterboxes on Atlas Quest with a special icon called the blue diamond. The blue diamonds are calculated from the feedback by those who have found the letterbox. Learn more about how blue diamonds are calculated, or rate the boxes you've already found.

If you go to the glossary and click on the blue Diamond, there are links in the description for you to see how they are rated and calculated.

She knows what it is. She was curious about the icon appearing in the comment, which was something she had not seen in the past.
