Question of the Day: Rewards Cards

I was just reading Jennifer Oppenshaw’s piece on gas rewards cards and it brought this question of the day to mind:

Do you use a rewards credit card? If so, which one(s)?

I don’t use a rewards card because it seems like it would be too much of a hassle. I like the simplicity of my Visa check card, that pulls money directly out of my checking account. No hassles and I don’t have to worry about paying another bill each month.

That’s my opinion. What about you?
