Wow nice to talk about this topic Mr. @binjeeclick, last time I had to read post by witness yabapmatt in Witness Update - SBDs, Meetups, and More!. The core of post I was underline about Liquid STEEM Post Rewards, according from him, This is because
the print rate of SBDs is increasing while the price of STEEM is falling which has increased the amount of debt taken on by the system in relation to the value of the STEEM which backs that debt.

In my mind, I think this situation was taken by steemit stakeholder/owner to be sure balance of market and social platform rewards.
