I've been using Mastodon – a free and open source, decentralized social media platform and a compelling alternative to corporate-controlled platforms like Facebook and Twitter – regularly since June of 2019. Mastodon is part of the Fediverse – a collection of inter-connected apps developed around ActivityPub, an open, decentralized social networking protocol.
In a recent interview, I heard J. Max Wilson talk about how he'd been doing a 7-day social media fast each month starting with Fast Sunday. That sounded like an excellent idea to me and I decided to adapt it for my own situation and give it a try.
