If you wrote 10 of those one would be a hit, I believe that. I think "code reviews should be converging" has good potential for a discussion. My model looks at the headline only and does not consider the quality of the post or any metrics thereof. I thought the article was basically right but the use of the word "converging" is unconventional.
