This is a fascinating idea @mindhunter. I think it speaks to the issue of allowing investors an opportunity to get out early with possibly less interest than the long-term holders. Personally, I have no intention of powering down until Steemfest 2 (if I must). Hopefully the weekly payout will cover my costs by then.
As for the vote slider... (sigh) I hate it. I think it's completely useless unless you're a mid-sized dolphin or bigger. I cannot understand why plankton and minnows want to vote 1% on stuff. really?!?!
