I understand the theory behind the proposed fix, but does it account for users below the slider threshold not being able to vote more often because they can't reduce their voting power? And does it account for users not understanding the slider or simply not wanting to mess with it? It introduces more complexity for the user and limits the activity of enthusiastic new users who will now be limited in their activity from the start.

It doesn't appear to be "friendly" to new users at a time when attrition is already high.

This also incentivizes users to simply vote for their own content at full power. Would this not have a negative effect for curation in general? Vote big for yourself, vote small on everyone else, and hope that enough minnows stick around to vote early on your posts in order to draw attention to them before they disappear into Steemit's black hole.
