I actually will do test with new users who have made very little or any with their post. I invited them for simple discussion, if iit was good discussion, i upvoted. Some would make a few bucks doing this. Also helped if it attracted higher SP members who entered the discussion.
The new users were simply amazed that if engaged with discussion they would make steem dollars and steem power. both as authors and curators.
I need to start doing this more!
Yes, I tried to upvote everyone in these comments once. I think authors should invest more of their voting power in comments on their posts - great way to encourage discussion and spread the rewards around.
