Many people set up servers so they and their real life friends can play in the same world together in real time. That way, you can both work on building a house, or a city or a world.

Larger servers have complex mods that add tremendous functionality to the game. Some may have roleplaying mods, where you can find a role (blacksmith, lumberjack, etc) and participate in the economy. Others may set up a world just for pure creation, a way to make sculptures.

There's a lot Minecraft has been extended to, so there are many reasons you may have to set up a server.

Thanks for the clear explanation. I somehow thought everything was in one "game world". The way you described it makes a lot more sense to me now.
