I don't see this as fundamentally different than the current voting weight (and reducing the maximum daily number of votes). Everyone can already scale the strength of their votes on the blockchain, it's just a matter of adding it to the UI.

In a sense we could limit everyone to 1 vote per day and redefine a "vote" as 5% of 10% of the current vote weight that everyone uses. That would also help equalize the organic vs bot curation playing field. Right now, achieving the optimal ~40 upvotes/day is quite difficult for regular users, so getting maximum curation rewards requires a lot of time that most of us can't afford to spend. It'd be nice if one could use their voting power for the day in its entirety split among a few posts if they're are worth it, as opposed to using only a fraction of your potential influence on the platform and being outperformed by bots.

Overall I like the idea.
