Fedi.TipsMany new people asking what Mastodon and the Fediverse actually are, and how servers connect to each other. I've tried to do a simple non-technical guide about this:
➡️ https://fedi.tips/what-is-mastodon-what-is-the-fediverse
TL:DR - The phone network lets you choose a provider and call people on other providers. Mastodon and the wider Fediverse do this for social networks.
If you prefer videos, these are useful:

J. Nathan Matias 🦣> In a 2015 lecture, Wreden declared that a “fearful state of mind” within the mainstream video-game industry had led to “an art form in which by far the most ubiquitous form of expression is that of firing a gun.” We have, he went on, “a culture where violence is understood and implied to be the central means of problem-solving.”
