This was a nice and short essay.
I think that it can be hugely motivating to see your essays reaching people. However, as the author pointed out, it can also be demoralizing if the ratings are lower than expected.
With that in mind, I don't think we should stop traffic analysis. The issue seems to lie in our initial expectations. I plan to apply some analytics, but I don't necessarily anticipate high ratings.
Also the author probably isn't advising us to completely discard analytics. He actually provides us with a simplified method for it. I think what he tries to do is to suggesting that we should not obsess over it too much. I agree that if analytics demotivate us from writing, it might be best to completely remove it.
