I'm amused that our brains went to the same place for Ferengi/Slytherin and Vulcan/Ravenclaw. I mean, ob-viously, right? ;) I couldn't think of good ones for Gryffindor and Hufflepuff or I would have done the whole set. I almost was thinking that in Next-Gen terms at least, that humans are kind of like Hufflepuff, what with how by then we've learned to work together and share resources without monetary enconomy and generally be the quadrant's nice guys.
