Don't give up on Steemit, there are plenty of users who are interested in many other topics, start by following some who post content you DO like. You will see a huge range of interesting topics including those you are interested in. Try not to be too worried about the rewards, just find users in the community who you enjoy being social with. post your stuff and have fun rewards will come to those who wait. (I'm still waiting). You've got to admit getting any reward for interaction in a social media platform is something cool. the all adds up...bit by bit you and I will get there.
