Markus Alexej Persson (aka Notch) has stepped aside as lead developer on Minecraft. He has handed over to Jens Bergensten "as of yesterday".A note on the 'Word of Notch' blog states:
"As of yesterday, Jens Bergensten is the new lead developer on Minecraft. He will have the final say in all design decisions, so he will kinda sorta become my boss, I guess. I’ve promised him to not pull rank. ;)
We’ve been working together on Minecraft for a year now, and I’m amazed at how much in synch we two are when it comes to how to design the game. And when we don’t agree, we discuss it and something much better comes out at a result. He’s truly a great person to work with, and I feel very confident handing over the leadership of Minecraft to him."
