May I ask you what is the idea behind this @penny4thoughts? Or direct me to some post about it? I would appreciate it

I never actually published anything about it because I don't want it to grow faster than I can keep up (it's been running for a long time, but I'm just a weekend warrior. ;-)

The idea behind it was I thought that reward sharing would be a way for small stakes users (with limited upvote power) to compete with larger stakeholders for engagement. So, even if I can't give a $0.25 upvote to someone who replies to my post, with quality content and reward sharing, I might be able to give a STEEM or two from my author rewards to the people who reply to my post. This comment that @chriddi already linked to has a basic description of how it works.
