At first glance, the steem fish scales gave me the idea of a food chain. When I started to read the comments here, I realize it is based on the size.
Feedback # 1: Shark is better to represent the size
Feedback # 2: Define by Steem Power
Feedback # 3: Prefer using SP native to the account
I feel that the delegation would create more confusions and misunderstandings. Even now, I felt hampered by the voting power (20 votes/day) and because of this some good post are left vote-less.
In my opinion, the move of classifying the account according to SP delegation, will hurt the curation activity even more. Just my two cents..
thank you.
