I try to make all my posts meaningful but I've got that only my posts from time to time.
Peoples saying 'thanks for sharing' or 'nice post'.
The worse one I've had is one I was opening up about a friend who had recently ended his life and someone commented 'haha this is funny'
Although it is great steemit is growing, it also comes with spammers and trolls which is annoying but we will have to deal with it @blocklab
