Can you check the 1st prize winner and share how he won? What's the criteria you found in his article to announce it as the no. 1?
His blog contains no article other than hashmart, isn't it odd that all of the discussion on that article was done almost in a 2 days (August 27 & 28) and there's no more discussion going on after that day.
As we said, we liked what he posted that is why he won. The number of comments is not the one and only criteria anyway.
We can assure that he is not anyhow associated with us, if it is your concern.
