I think you have to just ignore what people think and do what you do. This seems to be Notch's way of doing it. More power to him, I say.
I'm sure Steve Jobs didn't care what people thought of him either. He just defaulted to "they will love what I do because I will create something great", whereas Notch seems to be more like "people are trouble, so go away." Which would probably be how I'd do it too.
You can't always catch lightning in a bottle again. And I don't envy having that hanging over the heads of oh who am I kidding I would totally love to be in the position of potentially disappointing thousands of fans when my next comic doesn't appeal to as many people as my most successful one did.
