Not same curation and DV value for all. Simply remove DV option. Those who have more stake vote higher and get higher votes (as it already happens) and let small users get their own upvotes as they can. They barely put a dent in the reward pool.

You don't see the issue of a powerful user nuking someone else just because they don't like them? Look at my posts. I used to post everyday and my posts were very underpaid for my efforts and when compared to so many other posts. I still did it until azircon nuked me forever.
