Both were(are) homepages that list your likes/dislikes/memberships and have a stream of comments. It was friendster et al that tried to do the real hard CS graph theory stuff. Facebook /still/ doesn't do those things - though they talk about "the graph" constantly. Just try searching for everyone within X miles in your network.
