I don't know, but definitely not my content.
Probably the high amount of Steem Power of the author, but that is not a content category. I guess that the content category is not matter, as long as you have a high amount of Steem Power, which I currently don't have.
The higher amount of Steem Power you have, the more people (at least pretend to) care about your content.
I usually earn a few cents (a fraction of Steem) with my posts, because almost no one cares about my posts, no matter what I post, what I try, what I write about.
Nowadays I have a low amount of Steem Power. Nowadays I have less than 300 Steem Power.
I currently (2019.02.14, 16:18 CET) have only 256.848 Steem Power.
