If you're going there on vacation--don't. Africa in general (there are exceptions, of course) is not a nice place to be.
If , on the other hand, you're into missions trips, or working with the peace corp or some similar organization...I don't think you'll find a spot more in need of it.
However, with that said, the people there are wonderful, or at least all those I've met have been. (I've never been to Africa, but I did use to work with a local nonprofit, and they had a lot of people visit from Africa.) But I still wouldn't recommend the continent on the whole as a vacation spot.
