Help me, I can't figure out for the life of me what this is.

It suggests to put in "Rob" as a name. I do, I hit "explore", and it says "Alaska 0" and the map is completely white. I try hitting the down button and the map is still white. I try dragging the slider, and everything's still white, except occasionally some state turns a very light gray. (Chrome on OSX.)

I try putting in multiple names, but it still seems to show only the first one in the map?

This needs some instructions/explanations. And from the HN title, I thought this was going to be something about names most associated with rich people...
