I left a reply in that post about how you can't expect overnight success on Steemit just as anywhere else. If you started a Youtube channel or a blog with the idea of being an overnight success, you're barking up the wrong tree and headed for disappointment.
Most people work hard at these things for months or years before they succeed. Plus so many of these people complaining don't even bother to read the work of others, yet expect everyone to read theirs. I don't have time to vote and comment on a load of posts every day, but I do whenever I have the time. I just can't wait to have a vote slider so I can actually vote for more content!
