Lowering the HBD Apr might people to stake more HP and join in the Governace :D

When you use the word "might" you are saying to yourself that chances are "governance" won't be impacted either.
It is only a possible remote benefit.
We have a visibility problem, the experiment of having 20% APR has not worked because we are not visible (THERE IS NO MARKETING) but it has not harmed the HIVE Blockchain economy either.
Everyone is speculating about something that "could" happen but doesn't and I doubt that anything will happen but, going back to the topic, why can 15% be better than 20%? And why not 0%... everything seems very arbitrary to me, really.
