The order of the ‘top’ titles is determined by the moderators (they ‘pin’ posts to the top) and the time decay formula (a 12-hour-old post must have 10 times as many as a new post — more info at Reddit_for Beginner), the score is the number of upvotes minus downvotes. Take a look at the sid_compound (sentiment analysis score compounding positive and negative…
