Community builds generate in world

I got this idea from Lego. So, Lego has this thing where you can submit an idea for a set. If your idea gets enough community supporters it has a chance to become an official Lego set.

Now, I think this idea can easily be extended to Minecraft. The community would be able to suggest builds they would love to see generate randomly in the Minecraft world. The most upvoted ideas have a chance to actually become a real Minecraft structure.

I think this idea is great because it's an easy way to introduce a lot of variation to exploring in the game, while Mojang doesn't have to do most of the work. In fact, they can remain in full control as they can always decide which builds meey their quality standards. Anything they don't like, they just reject.

On top of that it's a great way to include the community in the development of Minecraft.
