In fact, I do not even know what I was upvoting. Good catchy titles, smap for the masses... cute girls... and I was upvoting.
I had this strategy of running down the "ACTIVE" list, and see posts with already $5 to $20 in the list, and then I would hope that they will continue to climb.

curation reward of 0.012 STEEM POWER for jrd/arrows-of-the-leviathan-prologue-and-chapter-1
Fun fact: the author had been considered as stealing content by a bot...
