Local communities all operate in the same time zone. No reason small online communities couldn’t operate in the same time zone, allowing each time zone to have their own separate communities.
Expensive long-distance phone calls sucked, but the side-effect was that nearly everybody on a given board was in the same or one-adjacent local calling area. They were strangers behind a screen only to a degree; they were also your neighbors, schoolmates, and coworkers. If someone needed something, someone else could bike or drive over and help. We had parties, we had picnics, we organized camping weekends. They didn't stay strangers for long.
Yes the global internet was big and shiny and it let you talk to anyone anywhere. So far away that they might in fact be a dog, and you'd never know. But for all we gained, we lost that sense of local connection, and I didn't appreciate that aspect until it was gone.
Then again the drama of Nextdoor communities probably means this is largely dead...
All of the (continental) US is in similar enough timezones, that whatever 3 hour window is convenient for one part is still easily accessible for the others.
You can also add Arizona to the list, but for only part of the year, as Arizona and the Hopi nation do not follow daylight savings time, but the Navajo nation, which fully surrounds the Hopi, does
Those small shifts don't transform a convenient time into 4am.
Sorry, what does that mean? What are phone wait times, and what do they have to do with time zones?
For example, Finland, Romania, Turkey and South Africa are on the same time zone.
