I love that the 19 Clicks articles reference the 6 degrees of Kevin Bacon game. Still this is fascinating, it sounds like a lot to me, if you count getting to Google (1) then searching (2) then links on the first results page would be (3) so I wonder if 19 has any relation the amount of search result pages one might encounter? Although people rarely go past page one in their behavior in actual links each page of results could be another click.
