Notch clearly disagrees: "The game is still extremely early in development, but like we did with Minecraft, we expect to release it early and let the players help me shape the game as it grows."
Design by committee ("the players say they really want X, let's include X") is not the same thing as design with consideration of feedback ("the players really liked X_0, let's build X_1, and deemphasize Y because it didn't turn out fun").
The fact that you're looking at the site is all the feedback he needs.
It's interesting the first iteration of the site was actually on April fools day, a good way to withdraw the idea if it sucked (no withdrawal needed ; ) ). I'm guessing but I wonder if there are more sites out there with slight variations on the idea to determine which one gets the most exitement and spreads the fastest
