I do exactly what you do. I got the highest percentage cash back credit cards I could find. Then I started charging everything I could on the cards and set my bank account to pay the cards off in full every month. I just reap the cash back at no cost to myself.

The rewards aren’t huge, but if I can save 2-3% on my expenses, why wouldn’t I do that?

I have a Discover and a couple other cash back cards. The Discover has quartely rotating 5% cash back categories, and the others have different deals from other merchants, as well as a card that is always 2% cash back on everything. I simply pick the card that maximizes my cash back, and pay it off as soon as the charge clears.

At this point I've made hundreds of dollars from the CC companies and haven't paid them a dime in interest.
