It's actually very useful if it can detect with reasonable confidence that there is a person in a picture. One example of a use is at Kiva we require borrowers to have a picture of themselves posted for their loan. But sometimes we get pictures of things like goats or cows instead (those are kind of nice to but gotta follow policy). Currently this is something we have to manually review for, but if we could automate that review piece it would save a lot of time (especially if at some point it could also count the number of humans in a photo).
