I don't think that it is only the content that makes you get lots of up votes
i have seen steemians who post a very poor content but rewarded tens of dollar without promoting their posts.
Am tired off entertaining only couple of up voted which finally ended with no rewards
Really am tired off and in about to make a decision
Either I have to see many up votes for my posts or otherwise decide to quite spending time on steemit
Why others only...???
