everything you post is good sensei, its only that this post has been nominated by curie. Curie is a scout group that scouts a good post, once you get curied once to three times, the chance of getting curied is smaller. Things are different here, its not like youtube, like when you have many audience or viewers you will gain more. Here, in steem, even if your post only has been visited by a few, it might still gain big if it is upvoted by a whale(someone with big Steem power) and curie is a whale. That is the case here, jsut look at your wallet sensei, you have steem power too, it only happens that curie have 80000 steem power.
