Well, It all started when I was just going to make a world to blow up with TNT. So I make a new world and all, and I notice that theres only like 5 blocks of grass where i spawned. Of course, I was in creative, so I pull out a map from my inventory and walk around the whole map. And guess what I found, water! Nothing but water. Blue as far as the eye could see. If you would like to see for yourself put in this seed into your 1.1 world generator, 5727107282168095940 (Be sure to make sure its not on superflat!) I just thought it was wierd.... :P
