A "minnow" is someone on the site who does not have a lot of Steem Power. All the "little guys" in comparison to the "whales" that have millions of SP/voting power :)
There are "dolphins" too, which are somewhere in-between. I totally agree that someone should put this all together into a table! I wouldn't be surprised if there were several posts about it already :)
I was just curious when you are no longer considered a minnow. For instance, does the payout from this posting change my status? Am I like a goldfish now? An infographic with this as a joke would be cool. I'll see if someone has posted one already.
Hehe, goldfish. I like it :)
I don't think there are any defined cutoffs. It's somewhat subjective :)
