by what "official" means will they be announced?
Will the mechanics of posts that are voted on and earn Hive still exist, or is it just a present day thing only?
This depends on Hive consensus.
Personally I think it's smart to continue issuing inflation in this way, but not everyone agrees.
What role does HBD play in all this?
HBD is an algorithmic stable coin that can be thought of as "Hive's debt".
HBD is also "bad money" that will eventually dominate the ecosystem.
HBD allows Hive to control it's own stable asset and piggyback off the FED.
I'm a very big fan of HBD for myriad reasons.
It's a great way to provide stability and outsource our inflation/debt to another asset class.
