Do you think debit cards should affect your credit score?

I saw Suze Orman a few weeks ago on TV talking about the new debit card she is offering. During the interview she said one of her goals is to have debit cards influence credit scores. I see the quandary that those trying to do the right thing financially, possibly including cancelling their credit cards, or young people who do not have credit cards, have some trouble building credit, but I don’t see how a debit card proves someone is responsible with money or credit.

What do you think?
