Communicationception Culture: 

There was a website I used in school, it connected people online through snail mail emulation.
So basically, you write a letter, it would either be physically sent -
for risk of DOX (they upsold virtual POBOX) or emulate speed of snail mail digitally. lol

OMG I used a similar website years and years ago? It was called postcardx. it was real snailmail and you would send letters to random ppl
