Jarvik's Heart Not First In Museum

I was just in D.C. last week at the National Air and Space Museum and they housed some of the exhibits from the National Museum of American History and this was one of the pictures I took of the first artificial heart. It was constructed in 1969 meaning that Jarvik's heart is not the first in the museum.

Negative Count for Digg Story

I am linking to this blog because digg won't let me link to the original digg story.
The link is http://www.digg.com/football/Louisville_Cardinals_are_Orange_Bowl_Champions

I was pretty impressed, I submitted this story about the Louisville team that won the Orange Bowl last night and the story now has -1 diggs. I believe that this is a Digg Exclusive.
If anyone knows why this is then let me know. Otherwise, haha to everyone who wants negative diggs, I am the only one.
