In the Central American village where my Great Great Grand Mother Felitzapec gave birth to my Great Grand Mother Felize and sold her to The League of Scientists for coffee beans, there was no social media. All communication was by word of mouth or by inserting messages into goats.
Now however moreover in this day and age, it seems to me that the whole planet is forgotting the benefits of goat-mail: environmentally good, affordable and milky.
