Right, I don't quite understand the logic that he used to determine what post would receive his attention. Steem generates an amount for curation rewards each day. If that reward goes to one user or another, it does not effect the price of Steem and whether or not that content is evergreen or digestable within 7 days, again is not relevant to the value of Steem. To grow his investment and thusly the whole ecosystem he should be upvoting various well written content. Not downvoting. Downvoting should be used to get ride of the spam posters and make it difficult for them to post.
