wait so you switched off of LongFast, the channel where all the organic community is because it's the default and has enough range to tackle decent distances, and are now posting about how empty it is as if MediumSlow is representative of meshtastic as a whole?
I can get hundreds of nodes in my city on LongFast, there's a robust community mesh, but if I switched to MediumSlow I'd also get zero peers, because nobody uses it rn. Non-standard channels are only useful if you get organized (my local mesh has talked about switching over to a different channel as a group), or are using it for personal use with your immediate crew and have your own router nodes if necessary
