I had a local burger joint call me up to tell me that the our food was currently, and had been with the driver for the past 30 mins. They knew this because the guy decided to have dinner in the parking lot after picking up our order so I really try to avoid now

I thought about that too, but I also can see a scenario where as the userbase grows, one instance’s community is seen as the “default”. I suppose the upside is that if something happens to one instance, there will be a backup of sorts on another instance - which in a way is sort one of the points of decentralisation.
