That's funny, I wore my SteemFest pin while visiting a friend. After a while he googled Steem and said "I knew I saw that logo before". In fairness, we had been discussing SteemIt before that.

At work, I drew a Steem logo months ago on a whiteboard. It's still there although I doubt any of them are aware of Steem. But just hanging my SteemFest scarf with my coat puts the logo in a second place [a small number of] people will see it.
