It just goes to show that social proof is extremely powerful. 1. Create a really crap game that's not really a game.
2. Create a site with a bullshit stats page showing how many geeks are supposedly buying it and how fast.
3. Spam about it on geeky sites.
4. Watch all the geeks throw money at you as they try to prove that they are geeky enough by buying a sandbox game that they "totally get."
Mojang, I salute you.
