Mypoints; How bad?

Has anyone ever noticed that the http://Mypoints.com symbol is a pyramid? As in scheme? I use the site as an occasional source of free gift cards (I flick through the emails and surveys, never giving out my credit card number), and am wondering if I should quit before I get too deep.

Not only is the symbol a pyramid, but also they advertise for some interesting clients, esp. Countrywide Financial.

Any thoughts, experience, or horror stories?
