There are many ways that information can be gathered and disseminated in a post-disaster environment. It has been my observation that most folks in prepping circles are aware of this, but we as human beings have a tendency toward tunnel vision on some things and ignore others. This is often to our detriment. Information gathering takes many forms and goes beyond the technology involved. By our nature, we, preppers, like to focus on mechanical, technical, and logistical solutions to problems. These are all important things, but it also means that we may inadvertently compartmentalize our thinking, and thus we don't really see the big picture.
