It also depends on the limit you play at.

I play at Low-limit games now, and, looking at poker tracker, realize that i earn no profit from any Ax lower than AJs. Every hand above i'm making money, big money, every hand below, lose money.

However, this doesnt keep my from playing it because I too know that there are tons of people that play Axo. I even play A10o for some reason, i just cant pull myself to fold it. In the last day my A10 has lost to an AJ and my AJ has lost to an A10 so i would agree with everyone else.
