Great advice! Enjoy tuning in every morning to hear what you have to say. Steemians like yourself are leading the way and giving smaller minnows a window into what it takes to succeed.
RE: comments. My background is in traditional media, and the "comments" sections there are usually toxic. In fact, many media organizations simply turn off comments after a certain point (or strictly limit who can comment) because they provide such little value. But that's one thing that I really like about Steemit -- the comments are generally positive/supportive and filled with unique insights. They are worth "upvoting" because they really do provide value.
You bring up a valid point. Most comment sections are whine and bitchfests.
Not on Steemit. Comments are meant to add to the conversation. Trolling tends not to get too far since we see people jump all over that person. In that regard, the downvote button is very helpful.
