The truth is that upbuilding comments builds ones spirit to write more, more to that steemit is a social media platform and from the little I know social media means chat me I chat you, reply my message on the group I reply yours so conclusively conversation and commitment is an important quality of an active steemian.
Even the steemit team encourages us to build our voting CIS by voting and commenting on other people's page.

Like the example if I make a post and there is no comment honestly I always feel like maybe my English are not well arranged and it makes me sad, so let's read and make quality comment.
