Many 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:

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:

@Gargron @thomasfuchs @VojtechHorky I'm not sure if this is related but I just followed this chap on a different server and 30 min later I still don't see any of his posts.
@Mojeek thanks for the reply! Happy to engage with you here then π
Glad to be part of a rare breed and very appreciative of your continued hard work so we all have a true alternative to "AI slop."
@Mojeek switched to your engine as my default on #Firefox this week. Truly appreciate the hard work you are doing to be a true alternative.
Any chance we will get an update to the great search engine map you made?
Also, curious β which social media channels do you see getting the most engagement these days? Hard to keep up with all the new ones like #threads and #bluesky etc.
Just wondering which network has the most search engine geeks π
