Back when I was a teacher, I always noticed that some students don't speak up even when they have the right answers because they don't want to sound stupid. It's like that for comments too sometimes. Some steemians are learning English as a second language, some are shy and some are just amazed by a post but don't know what to say about it other than 'Wow!'. There's room for all types of responses so I try to give people the benefit of the doubt before deciding that they're bots. Great name btw!
