According to the website:
CharityFocus has no paid staff members. A common downfall of nonprofit organizations is that their pure intentions are often overshadowed by the challenges for survival. What begins as a way to serve others, very easily becomes a self-propagating system that aims to stay alive at all costs. Noticing that trend, CharityFocus took another route -- keep the organization fully volunteer-run. No money to raise, no vested interests, no hidden agendas, no image to uphold. So long as volunteers give, the organization will continue to thrive.
It's gloriously utopian:
CharityFocus has no leaders, no followers; its strength comes from its emptiness and its beauty resides in the hearts of its volunteers.
Take a look at their programs. Amazing. I'd tell you to donate, but I don't think they want your money.
