The official Mastodon app is doing something new which is potentially very dangerous to the existence of Mastodon and the Fediverse.
The official Mastodon app now prompts users to join mastodon.social by default, when previously it prompted them to pick a server. If you're new this may sound harmless, but let me explain.
The entire point of this place is to be a social network spread out on as many servers as possible (the reasons are here: https://fedi.tips/why-is-the-fediverse-on-so-many-separate-servers/).
