There seems to be a bit of confusion between examples of "six degrees" and interesting stories of coincidental meetings.
   *I* once met a guy I knew slightly from Iowa in a store in Juneau, Alaska....but it has little relevance to the six degrees idea. I enjoy the stories, but they are a bit of thread drift...(what! thread drift? here at Mudcat? )

I repeat...those who claim 6 degrees need to specify how well one needs to know anyone in the next link.
