Considering the amount of tech and self hosting types that live in cities, it seems like it would be popular to have little mesh intranets all over the place, but I’m not aware of any.
I read about NYC Mesh a while back, and I wonder if there are other similar things already in widespread use that I just haven’t heard about.
I haven’t been on there a lot and due to time constraints I’m mostly just lurking. It seems that I can see more people on Tastic but Core seems to be more active in terms of messages.
Both are almost absurdly easy to set up, especially on an nRF5-based device where you can flash a firmware by just mounting the thing as an USB drive and copying a file over. You don’t really need to buy two devices to try out both unless you really want to use them simultaneously.
