The Mastodon network is perhaps the most notable and successful platform in the fediverse. Founded in 2016, Mastodon has positioned itself as an alternative to Twitter -- one that can be completely under the control of its members, from it to its daily operations to it underlying software.

Making a noncentralized, ethically-run social media system is no easy task. The people building the fediverse have faced burnout, bigotry, angry debates, and death threats. And they face constant, nagging doubts: can we really do this? Can noncentralized social media survive? Can we -- all of us -- have our own social media? In this thoroughly researched book, Robert W. Gehl argues that the answer is yes -- but it won't be easy.
