I've been curious if the functionality for more decimal places is built in or not. I think it is definitely needed. I agree it would already add a "scoring mechanism" and some progression that minnows don't get even now. It becomes much more important if we get large influencers on the platform publishing content that may gobble up the lions share of daily rewards. More decimal places are also inherently needed to deal with a hopefully increasing value of steem as well as the reverse splits that will regularly occur. Interest, content, and curation rewards should all pay out in very fractional amounts if the system can handle it, so that everyone makes incremental progress with their interactions, however minimal.
