On October 4th, 2001, I read this post https://tech.slashdot.org/stor... on slashdot. The article it refers to, http://archive.oreilly.com/pub... describes "SMS Relay -- An Idea for Fault-Tolerant Communications", wherein the author proposes building a mesh-like network capability into the SMS programming of cellphones. It's still a good idea.
And that article got me thinking about what I could do to make a difference. I shortly got my first ham radio license, volunteered with ARES, then the Red Cross, and now work there.
