I introduced kbin to someone today who asked what the fediverse was. I answered for them of course, but it made me realize that the concept is still technobabble for most people. The average joe probably doesn’t care or notice that server A is really talking to server B. Just have them find out on their own and if a mass migration does need to happen from A to B, just make a standard announcement.
This is not 100% true.
A good comparison might be World of Warcraft. While not the best example, a player does not have to be in the same instance/server as their friend in order to join in each other’s content/dungeons. This is a fairly new feature of WoW ( and not feature-complete compared to full federation ). It could stand in as a starting point for the conversation.
most people have not played WoW or any MMO
Most people haven’t used Twitter or Reddit, either.
