Novelty

If you do something in a fundamentally dumb, backwards, or inefficient way, the result may not be good but it is very likely to be novel.

I had this thought while writing code to make graphics out of over-lapping CSS shapes for a Rogue-like web app game, but I think it has generall application. If there's some genre where nobody else uses a certain technology or approach because it's obviously a Bad Idea(tm), but you do it anyway, then (whatever the flaws of your final product) it at least won't look like a cookie-cutter copy of all the sensibly-designed alternatives.
