My idea how to make Premium more attractive is to be more clear on how the @leo.voter upvotes are chosen, so people know more consistently if they'll get upvoted or not.
Many people are considering LEO Premium because of the "Premium Pays for Itself" line, and they're not sure if they'll get upvoted.
They release thread and post on sunday explaining how the leovoter curation works. Based on your leo power staked you get more chances. CUB and higher ranks get the more chances. But still no assurance.
Hmmmmm.... Interesting!
