But a rudimentary seasoning is really easy:
Wipe some oil over the pan. Use as [high temp oil] as possible, but whatever you have will work. Wipe off any access with a paper towel. Put it in your oven at 230(C)/450(F) for at least 30 minutes. (careful it will smoke a bit).
I couldn't recommend using it at all without some base layer of seasoning. It's really easy to do and lasts quite a while, even if you don't follow the articles really thorough methodology.

[high temp oil] aka those with the highest "smoke point" http://en.wikipedia.org/wiki/Cooking_oil#Types_of_oils_and_t...
If you don't want to use flax seed oil, just use canola oil.
I've got a newish, rough Lodge and a vintage smooth Wagner that I both stripped and reseasoned (with just Canola oil. This flaxseed method is overkill IMO). The Wagner can cook eggs like teflon; the Lodge, even after two years of heavy use is still pretty rough for eggs, its nonstick enough for most other foods.
Cast iron is nice and I prefer it for its properties besides the nonstick abiluty, but for the casual home cook making eggs, Teflon is pretty foolproof.
Doesn't it just provide a very hot surface that boils off any local moisture? That's would happen with a cast iron skillet.
It would explain why cast iron pans or glazed earthenware is used for baking no-knead bread.
I used to own a pizza stone that seemed to transfer a lot of heat to my bread, even though it was relatively thin and didn't feel very dense. Bread and pizza would brown nicely on it, even though it was too small for baguettes. One day it cracked and I bought a different kind (Ceramic Chef brand). It's a little thicker and feels more porous, and I just can't get crisp bread on it even after pre-heating it in a 500F oven for 30 minutes. The new one is definitely a different type of stone. Maybe it's engineered for people who want to cook on rocks but don't like crust?
I'm excited about baking on a large slab of cast iron. I've had a 12" cast iron skillet for ~15 years and use it all the time.
