I've been on the receiving and perpetuating end of state machines and it's painful to have to deal with one that started years before you got involved and easy to think that you can do better. I've got a modest one in a side project and due to it being a side project I touch it once every couple of weeks and already it is making me uncomfortable. And it's dirt simple and I wrote it!

There's a take on state machines in a railsconf talk further down in the thread and it seems like an awesome way to reap a lot of the benefits while keeping a grip on the complexity. Sometimes complexity can't be buried safely and you kind of need to frame it instead. I'd argue that state machines bury that complexity but breaking those states into ruby objects w/ their own validation frames and delineates them instead.
