Don't be torn. You never would have had me even try your service if you asked for a credit card. I suspect its the same for most people.
Getting a credit card later is proof that you have made an invaluable tool that people just didn't forget to cancel, and should make it easier for you to adjust your service until you hit the sweetspot and become a must have.
