I was thinking about semaphore, the ancient system of very fast communication. You put a team on the top of every ridge between the country's border and the capital. You equip them with a messaging code and a means for sending messages to the next ridge — flags, smoke, flashing lights.
This kind of system still works. A few years ago my students and I sent a message around the perimeter of a very large university building in 4.5 seconds.
System requirements
At the edge of the country, or in any other danger zone, you need a team watching for hints of enemy action. They have a job that they focus on.
The message teams on the ridge-tops have a job they focus on.
In the capital city, another team must be prepared to interpret the signals and to act on them.
Without these teams with focused tasks, we might as well plant flowers at the top of each ridge and go up there with a nice bottle of wine and sit in the pretty sunshine. Or we can sit at the end of the message stream saying "Oh wow, this is depressing" over and over again.
Semaphore is not broadcasting.
Most message systems we enjoy each day are, down deep, systems of broadcasting, even for those of us with few followers on social media. NBC and FOX broadcast to their millions, and people like me broadcast to my tens. Both are forms of broadcasting, in that seed is tossed out to whatever audience is there, and for NBC and FOX and most social media users like me, we behave as though that's fine, that's good enough. A spray of messages going out is good enough for most who operate on a loosely defined broadcasting model.
If our media tools were more like semaphore, and less like broadcasting, things might be different. Those who report on whatever issue, from whatever frontier, would not be satisfied with what I'm calling broadcasting. We'd organize at the send end, and we'd want a team at the other end that is organized around appropriate action.
The tools we have for the most part don't support organization at either end of the semaphore chain. Yes, messages go out from ridge to ridge, but there's usually no team on the frontier knowingly attempting a worthy shared task. And there's usually no team at the far end of the message chain focused on making use of the reports.
We have fabulous messaging systems undreamed of a few decades ago. We have for the most part not built the social and civic groups at each end of the message line to test the power of the tools.
It's a bit like a US Civil War army placing cavalry way out front to locate and judge the strength of the enemy, then send a message back. And even if you did have cavalry sending good messages, it's a bit like there's nobody back at the army's headquarters organized to plan a response.
