Sure, Mastodon is small in raw numbers, but we are big enough, a proven platform and an engaged community. If you act in concert you can bring a lot of your followers along. Before you know it we could have truly substantial and influential public social media that is not beholden to some billionaires or corporate overlords.
Understand all the reasons it seems like a big step, and it is, but for all of our futures, now is the time to pitch in and help build distributed public social media.
