I see where you're coming from, but it is not a penpal service either and they don't want to be passing messages. I traveled to a school in Uganda which had some students' education sponsored by Americans. They were real students, and the issues were usually student performance, if students had a problem or got pregnant would that affect their scholarship program and scare off the donors, etc. Knowing that it is assigned to an individual person is important for some people, but you might just want to donate to doctors, schools, etc. in general.
