I don’t think people involved in insular hobbies are any better or worse than they have ever been when it comes to gossiping/trash talking, etc. I just think the circle of awareness is much larger due to all our communication advancements.
You used to need to actually see the casual acquaintance/have an IRL convo with them to pass on information (gossip or otherwise), because most people weren’t going to get on the land line, tethered to the kitchen wall to pass on juicy updates or vent your spleen to a casual acquaintance. To a close friend/confidant? Absolutely.
So “mass” communication was limited to the barn or a show… and yet, it was always amazing how everyone knew everything. Now, with cellphones, social media, text groups and so on, it’s still SOSDD, but with a much larger circle. Technology has changed. Humans? #notsomuch
