To qualify just visit Mene and tell me your favorite 24 karat gold or platinum piece in the comments below along with why it is your favorite.

It didn't say anything about making a post just to explain in the comments.
The winner did not explain in the comments why that particular piece was so awesome, just backlinked to the post.

So I'm wondering why an exception was made to the rules of the original contest in order for nomadic to win.

Congrats to the winner tho. :)
