Why Mastodon As part of my self-hosting journey, I shut down essentially all my social media in 2019 with the exception of my LinkedIn, Spotify, and a twitter account which I used to follow but not to post. I didn’t think it was possible to really self-host social media, but the events of the past two months and the explosive growth that Mastodon has undergone has changed that. Regardless of what you think about the recent changes at Twitter and the rise of Mastdon in headlines, the idea of decentralized and self-hostable social media is super interesting, and totally feasible.
