These are the things that I had spend some time to learn even before I started to post here. I suggest it would be better to vote on the good @utopian-io posts to get maximum curation rewards. The 0.01$ upvote of mine is not going to make any substantial difference if I cast it on my minnow friend's post. It would be good to upvote only on posts having quality instead of upvoing on every single posts just because the post is of a friend!

Even I found that upvoting on haejin's posts can earn a lot of SP. I used to do it before I learned the word reward pool rape. Now I have learned the art of differentiating chaff from grain! :)
