you can also add a donation option underneath your posts. I am also sure apps can evolve on the steem blockchain to bring this about. note that there almost 500 apps already built on steem, so explore other interfaces to see what they offer. there are apps dedicated especially your passion that look to reward the content you make. you may find some on steemprojects.com

some of these apps already offer tokens called smt. smt capability will happen mar 2019, where everyone can create tokebs and communities with its own dynamics. explore some of these other apps as well. some reward tokens for extra activities, some just for having steem power etc
