I cannot well repeat how there I entered,
       So full was I of slumber at the moment
       In which I had abandoned the true way.

The Divine Comedy/Inferno/Canto I, by Dante Alighieri, Translated by Henry Wadsworth Longfellow

My point is, it's easy to get into this kind of weird design world, if you just do the quickest thing at every step, with no ability to think about how the big picture is going to look.

I'm sure nobody wanted to make a weird architecture, because they're harder to extend and harder to write software for, but if you always have the deadlines breathing down your neck, don't be surprised if you end up in a scary forest indeed.
