Its such an easy thing to do, but until you go start trying to maintain code that is poorly written, you'll never really understand WHY you should lay everything out nicely.

There are a number of tools on the market (or alternatively you could learn how to set Management Studio up properly) which will refactor your code, so basically I believe there's no excuse for poorly indented/laid out code.

I think every programmer should spend at least a year on maintenance prior to being allowed near a greenfields development!
