Hope you are doing great out there in the Summer weather. Some of us here at Mojang are off on vacation and some are still working hard in the office. You may have seen Notch tweeting about our deals we have with Humble Indie Bundle, where you can test out Minecraft for free when you purchase the awesome indie bundle where you decide the price? Or you may have also seen that you can get free in-game t-shirts in Battlefield Heroes? I was one of the alpha/beta players and the game is cool (love the aesthetics btw ;))
Why are we doing these kind of stuff? Because we love games and want to support other developers. And I mean, when you have cool developers such as DICE/Easy just a few blocks away, you know you are in a good horde!
