"There is absolutely NO monetary incentive to flagging posts, like there is upvoting. I could increase the Steemit circle jerk like many you see me flagging, or, I can take care of business and reward myself on this post. "

I am still an advocate of experimenting with a second voting (flagging) power, or X free flags per day.

Something, anything, to disconnect flagging from being totally anti-economic game-theory.
