The best example of federation I can think of is email. How you can communicate with someone using a different provider (server) than the one you're using (i.e. you, using Hotmail, can communicate with someone using Yahoo or Gmail.)
As far as this instance, it's really nice! It's really comfy, everyone is pretty nice, and it's just a fun place!
@easthighNerd so you're able to communicate with people in other instances as long as you have an account with an instance, like email providers? That makes sense, thank you! And hopefully this is a nice instance :D
@Elfie which languages would you use to create your own instance? Also, could you perhaps link to the big instances?
All your moe needs! A kind, generalistic instance where everyone is welcome! Important: if you sign up, be sure to check "spam" for your confirmation email if it does not appear.
