Hi Steemers (or Steemian? I don't know what is the official)
Today, I've posted Card News on blockchain which I created around a year back and shared at Brunch, a writing and publication platform available mainly in Korean). By the way, I found a steem mark on the subject of my article as below.
It was my third posting at steemit, and no other articles have any sort of mark like this.
Any idea or guess on this?
