It doesn't really mean very much at all. The technical part is that you have 1,000,000 vest that equals just about 500SP, The benefit is you get an easy vote slider to use. Steemit is organized by fish levels.
Redfish/plankton less than 1,000,000 vest
Minnow 1,000,000 vest to 9,999,999 vest about 500SP to 5000SP
Dolphins ten times minnow, each level 10 times above the previous.
I think those are the fish levels,
- Redfish/Plankton
- Minnows
- Dolphins
- killerwhales/orca's
- Whales
