At this time, I'm just going to wait and see how it plays out. I feel hopeful it will help new members feel like they have more influence than dust motes. That would definitely be a plus.
From a curation standpoint, I like the idea that I can (theoretically) give 4x more voting power to a piece of truly outstanding content. Because I do read and vote manually quite a bit, I will probably be voting a lot of more "average" content at 25%, which is technically about the same weight as right now.
