I believe this is a bad idea (4 week power-down).
The whole point of powering-up-your-steem is to take it out of circulation and stabilize the economy.
The longer you keep it powered-up, the more effectively it serves its purpose (13 weeks seems reasonable).
It also serves as a type of LOYALTY OATH.
A better "update" would be to give people the option to PERMANENTLY power-up-their-steem!!!
That way we could all stop hearing about the BURNPOSTS.
