Thanks for your post! It's very informative and answered my question: "Which kinds of topics earn more?" in great detail. As a member of the community, I think it's a good approach to identify a few topics I'm passionate about, and stick with a couple or a few ones that are liked by many (indicated by number of votes and the amount of payount). I'm currently in the experimental stage, trying to write about a large variety of topics and whichever ones become successful, I'll follow through. This article promped me to change course and analyze some data along the way.
