I'm sure most people will have seen this before, but I only came across it today. I was looking around at all the cool little tools google has and among them are some great stat generating tools. Like this one:
which shows the amount of google searches for lonelygirl15 and notes when there was media attention for the show. I think the pattern of less and less searches will surprise no one. But what i found sad was that July 2007 was the first month since Aug 2006 not to have enough search engine volume to justify a graph. On second thought, I think this might have to do with the google software and not the actual volume of searches.
