This is the Mastodon for web development (mostly frontend) people that are sick of Twitter. All kind of web development discussions are welcome, but you can talk just about anything except nasty/evil stuff. I always recommend getting your own private Mastodon instance at masto.host as it makes total sense if you think about it. You can find a beginner's guide here: https://opensource.com/article/17/4/guide-to-mastodon and a nice video here: https://www.youtube.com/watch?v=W22msAw2zwI&t=5s
Mastodon is a social network based on open web protocols and free, open-source software. It is decentralized like e-mail.
