Yeah, look me up when you've been cleaning up Rails code from developers who didn't bother to understand solid design principles for several years... that whole "wait til its a problem" thing falls apart pretty quickly in non-trivial domains.

You can't ignore things until it's a huge problem, that would be a mistake no matter what.

Do you have a real code example from a non-trivial domain?
