@BeAware Thank you for the explanation. So more visibility it is.
I do not want to hide boosts, because I like that people can reference others posts.
I just wanted to know why people do self-boosting even after some hours. But I guess it is the fast pace of the medium. People who consume a lot might miss posts as their feed is so crowded. I am used to travel slower as I follow 26 Accounts of whom only a few post a lot.
