The easiest way I can put this.
Want new content ? Cant have your old world.
Want your old world ? Cant have new content
We have likes? I'd give this a 'like'.
And I'll remind people again: Notch originally said there would be no more free content updates after Release. But we're still getting entriely new and updated content, not just bugfixes, for free.
So complaining "I hate (insert cause of rage here) because of (insert type of new content here)" is...well, I'm not sure what the word is, but 'ungrateful' is one that comes to mind.
