I was lucky enough to have my default spawn right in the middle of one. So now I have my HQ in the middle of a snowstorm. It's awesome. Plus I don't think corruption or hallow can go past snow so I have a natural barrier once I activate hard mode which should help keep the creeps away from my base.
When a true genius appears, you can know him by this sign: that all the dunces are in confederacy against him.
