If you look on Hivebuzz you are currently a 'redfish'. When you get to a million 'VESTS' (~535SP) you become a 'minnow'. It's just a way to track progress. You can also see the badges in peakd.
Ages ago I started a project to help minnows with the aim of getting 10,000 of them. We still have a way to go.
Have fun.
Thank you so much, Steve!! :) What a wonderful project! You have fun as well!! :)
