I like these ideas, generally.

1 - The system of votes should be the same, but by hiding the value of posts to the public, that forces people to be more selective in their votes. Not just voting for something because 20 people beat you to it.

2 - This is the by far best idea, instead of linking the value of a post to 'likes over 7 days', by shifting the rewards of a post to 'total rewards for that day / total votes for that day = rewards given to that post per vote received that day'. This way, a tutorial that might not have seen much attention in week 1 might still have value if a few hundred people give a thumbs up over the course of a year.

1. Resteems; because that's getting someone to show their audience something you may have written got their attention, perhaps a split from resteemed votes.

The point being, the platform has made all these choices that, because of human nature, actually harms the usefulness of the site and accessibility for new people without an audience.
