everytime I see this post I want to respond: EVERYTHING!

So I have a random question for you: how do steel cut oats differ in taste from, say, quaker oats? And how do you cook them? I was at the store the other day and stopped by the bulk bin section and saw steel cut oats (they look very strange). It said to cook them for 90 minutes. Egads, man- I don't have that kind of time.
How do YOU cook them?
