Minecraft Generation fail

I've seen bad generations, but my god! This has pretty much crossed the line for bad generations in Minecraft. Notch and Jeb should really get back to work fixing bugs, and not adding iron monsters into the game! The game has gotten pretty weird when you can walk 20 steps and go through a jungle, snow, and desert biome. They need better coding to mix the biomes and put some sort of blocker that prohibits a desert and snow biome to be RIGHT next to eachother. I mean COME ON! Comment on your experiences with bad biome coding, and your thoughts on this subject below. Thank you.
