Musings on German Excavator Posts

A la Borepatch, I just wanted to share something weird that has to do with Google Search.  If you search for "German Excavator,"  I am fourth on the list with this post.  It is currently driving about 10% of my traffic according to sitemeter.  Many of the people who come here through that post are international, and most don't bother sticking around.  I must not be what they are looking for... which begs the question, if they aren't here to see an awesome German excavator stunt, what kind of weirdos are they?
