This is awesome news - but I'm not sure I agree with the way you're utilizing the new vp. Although I like being able to spend 5sbd and get a major visibility boost, many users wont be able to consistently afford that.
It seema like a better use of the vp to figure out a voting percentage that works within the old payment structure. The result would be keeping the service open to all the smaller minnows while massively expanding the number of nearer 100 vp votes minnowbooster could make.
