You beat me this month, Greg! I had one breakout month in August. Scott Adams retweeted one of my articles, which drove a lot of external traffic. However, it only earned me $34. My best performing article was almost an accident, "5 Weeks and 15 Pounds," which earned $226. September was about half that, and then October about half again, even though Scott retweeted another of my articles. It seems that external traffic doesn't pay much.
