As a minnow I believe minnows should not worry about the voting power. On my first day, when I know nothing about curation, I simply vote whatever I like. Then, I discovered my VP was very low and I learned that I can get paid by upvoting other people. Now I know some tips to increase curation rewards. But even I apply all these tips, I can only get $0.001 for each upvote on average. Therefore, I won't worry about the rewards, just upvote whatever I like.
