Susie did write a great post about the smoking issue. Head over and check it out if you have time. It's a post or two down by now, but well worth the read down.
It's very interesting to see how different people do the same job. They all have different methods, different theories about what works and what doesn't, different ways of dealing with the madness, and vastly different understanding about how all the moving parts work. No great breakthrough here, just an observation.
My great breakthrough came after 4 out of 6 on a certain project and it pissed me off I didn't think of it sooner.
