It is cool! The barrier to entry is relatively low. The only thing to really worry about is:
What band/frequency is appropriate for you country.
Are there others around to which you can connect?
If there’s not a lot of people around it’s not the end of the world. Nodes can connect over the Internet via MQTT servers. Yes, this defeats the purpose of having an offline/decentralized communication platform, but it is a good stop gap until more nodes are put up.
Here’s a sample of what I can see in a somewhat large-ish Midwest City in the US (there’s about 63 nodes I can reach by hopping through relays).
I got mine recently in a dxent aized city and while there are plenty of nodes popping up on the map, the local channel is pretty quiet. Is that normal?
I don’t know. It’s the same for me but I got a pretty bad reception. The only time I saw some messages was when someone was sending some from a plane, so I guess it was a special occasion.
It allows us to make a mesh network (interconnected nodes where you can contact a node even if it’s not in range for you, by using other nodes) with Lora radio devices. Lora is slow but has long range. I think it works better when you have line of sight, like if someone can put a node on a mountain, it would help everyone.
I think people might have sent audio with it but it’s mostly useful for text messages. It could be useful if the Internet is down, maybe, but it’s more like a toy.
Ok…what’s meshtastic? I still haven’t clicked the article, and know nothing of which you speak.
I’d say this title is for people like me. I think it sounds cool.

Where’d you get that map from?
The official meshtastic app has a map view that shows all known nodes.
I got mine recently in a dxent aized city and while there are plenty of nodes popping up on the map, the local channel is pretty quiet. Is that normal?
Yep, that can be normal. For my city, the local group has a private (but free to join) channel that’s a bit more active.
Do a web search for meshtastic and your city and see if one pops up.

Since LoRa devices use very little power this can be useful when there is no electricity.
