I just finished this book. I really tore through it; could hardly put it down. Quite gripping story-telling, great writing style.. even from the first chapter.
I recommend everyone using social media read this book. Having used Facebook from the early days up to ~2015, it was quite eye-opening. 😳

Hey all, a few people have been asking about the retro game videos I have been posting.
They are from an old game called Emerald Mine (inspired by Boulder Dash).
I made a little video to explain it and show how to get Rocks n' Diamonds.
