My name is Eugen Rochko and I’m the creator of Mastodon, a free, open-source federated social network with over 760,000 users. You can check it out here. The Mastodon project is finally well-represented visually. I always felt like the previous logo did not do it justice. To its credit, it was both an M, and 3 sideways speech bubbles, but it did not scale well and overall it was just a circle.
