At its best, the modern social media landscape where the end user pays nothing to send their content to others is monetized in various unsavory ways. At its worst, it is used by those who wish to cause harm to generate divisive feedback loops that may very well cause the fall of society itself. What is a tweet worth? At one time, a short message delivered in a timely manner to one or more recipients was quite expensive. Slower methods of communication were less expensive, but still carried some cost. What would it be like to take the ephemeral, throw-away communications that make it to social media were instead sent via post to the same individuals one normally shared things with? I mean... if you're going to ask for someone's attention, at least pay for their postage!
