Hmm i don't know. But you bring up a good point about the rewards for resteeming. Maybe you should earn rewards based on your followers. They could make the algorithm as hard as you want to include the activity of your followers, the average reputation, their average and/or combined STEEM POWER and such.

Just checked this post (https://steemit.com/steem-help/@stealthtrader/what-is-resteem-and-how-does-it-work) suggesting that resteeming doesn't give curation rewards directly but if you previously upvoted the post then it may help increase the total post and thus curation reward. Your idea for a resteeming curation reward algorithm sounds on point - I would vote for that.

So resteeming gives you no direct reward. That's should be fixed probably :)
