A poor overworked guy just trying to help out when id hides from it's customers. Carmack today expressed surprise that the game was still broken in between tweets about his surround display and the Doom3 source code.
Now that's just not true; he did not express surprise, he just asked someone what was still broken for them. Doesn't look like hiding from customers either.
First step to fixing a problem is to find out what the damn problem is, you know.
