Kim Kardashian is a konundrum.

On one hand, she poses for bikini-klad photos on a trampoline, klearly attempting to garner headlines in any way possible.

On the other hand, Kim and her sisters are relatively harmless. They don't try to sing or star in movies or act any more important than they actually are.

Sometimes, in fact, they used their celebrity for good.

This past week, for example, Kim and Khloe Kardashian joined Reggie Bush in Africa. The trio took the trip as part of the Diamond Empowerment Fund, an organization that supports education initiatives focused on disadvantaged people on that continent.

Spending time with impoverished families, Khloe referred to the vacation as the "most incredible experience of my life." She wrote on her blog:

"We handed out food and milk to women and children and we got to play with the kids -- they were all SO adorable!!!!!!!"
