How do you explain mastodon to non-tech folks? Instead of explaining the federated social network concept, tell them it is like Email. You have Gmail, Yahoo, Hotmail servers etc. Similarly, you have a mastodon server, and you will have an address just like Email, and you can communicate with each other using that mastodon user name. What do you think? Can you do a better version? Explain mastodon to someone like they are five.
