I think baking in general is kinda procedure dependent. Can't just throw together the ingredients and expect it to come out right. I think sourdough is even more dependent on procedure.
I think there are two tricks to sourdough:
1. The culture has to be really active to do it's work; you're wasting your time if you use a flat starter thinking it'll perk up once you get it incorporated into your dough.
2. It takes a long time to rise, and you've got to plan ahead for that. I've had good luck putting the dough together the night before and letting it rise overnight. Then ball it up, make loaves, whatever, and give it a few more hours to rise before baking.
I don't think it's overly time consuming once you kinda get the hang of it. The steps are kinda chunked up too. I did another loaf Saturday night/Sunday that came out really good.
