Digg source code ... 959595 what?

If you go to Digg and view the page source, right away you see a comment that says digg is up 959595, now that's all it says. What does that number mean? Is that how many stories have been submitted to digg. I think that is the most likely answer. However it could mean something else. Maybe it is just a insider joke, that none of us would get. Who knows!
