Same node recommended multiple times

When I go to /recommendations, it shows me the same node 4 times. I don't know if that's because I have multiple Voting API modules enabled, since I'm doing testing, or because I only have one node. But at any rate, it probably shouldn't do that. :)

Overall though, this looks very cool! Sorry about the bug reports, I just figure if I run into them other people will too. :)
