Hello everyone, I know I am late to the party, but I wanted to be part of this amazing contest.
The first logo contains three different shades, first is when you post it and you don't get too many upvotes (being a minnow), second is when you get a few upvotes, and the last shade represents when curie upvotes it.
The second logo is simple, with small blocks and an upvote sign. The small blocks represents all steemians.
