> 10's/100's/1000's of nodes all hitting refresh on twitter

That's not going to happen with Lora. This it completely different scale of messaging. Your message is limited in bytes and takes multiple seconds to transmit. You can assume the messages will be significantly delayed if 100 people around are actively using it.

But it's designed for a specific purpose and there's no active refreshing/polling that's going to happen.

Exactly. How many people could this support? My guess it would be a small proportion of an urban population.

Maybe not twitter specifically, but the paper mentions a centralised message board like twitter, so we can assume some sort of interactive service would be suggested.

My main point is this that for such a specific bearer (bandwidth, channel plan, duty cycle, range etc) it is important to model the capabilities. I’m not sure how well this would support a crisis (notably free of central management) when there is the potential for large numbers of nodes.
