As someone who like exposure for their content in a regimen to get better at wirting & what have you, I can second your notion. What we need more is feedback. Like those times seen as on facebook & youtube. That at least alleviates the problem that not everyone who reads your stuff leaves a comment.
Of course on way to increase the comments is to write more engaging posts, but currently it is hard to see, if your post isn't that cool, or that noone saw it for whatever reason.
One thing that steemit does for me, is making getting better at what I do into a game. Which is exactly what I needed for ages now. So thank you for providing it!
