The decrease in power down time is important. The positive psychological effect will encourage powering up. Now that the user base has so many smaller share-holders it's good form to make that change. combine it with a stable SDB peg, encouraging people to hold SBD in wallet without concern; there's convenience factor there and it seems less like spending money to power up, further mitigating commitment concerns. That way to optimize the user base (already here!!!) that will not invest from their own pockets, much needed.
If the Steem volatility can be good, the upcycling possibility can build the vests of the average end-user here. It will become easier for people to see that possibility and its value (and become safe to promote to people) It's simple to stick to one crypto economy for most, especially for the average user, people who are introduced to crypto through Steemit.
Taking advantage of their interest in growing the platform, a reasons for staying and wanting to gain influence will bolster the steem economy. These changes will build the middle-range trickle down economy from the current dedicated user base who is already curating frequently, and invested psychologically in this online community. All necessary for growth.
Looks like most people approve the power down change. I hope so!
