I do not agree with you in some points. Nobody come and upvote your post except your followers. You need to advertise your content(your post). This is like tip jar effect. If your post have high payout people are interesting. Another way is you need to have a lots of influence on steemit. People come and upvote your posts to get your acknowledge and expecting your upvote. You have to be a star in steemit to get the attention of people.
