PR is mostly about opportunities, but some PR opportunities are created. It is a well known technique to create a survey that might be controversial, or at least "interesting" and use that as fuel for a press release perhaps even annually.
This enterprising individual generated great blogosphere coverage by graphing an interesting google query. Via Dina, the graph (to the left) is generated from a google query with alternating countries. I doubt a scientific method of sociology was applied, but it passes the "I find it interesting" test. Great job Radio Blogs.
Just to repeat, literally, this press was generated from a map with labels and 50 to 100 searches in google. That simple. Strategy is more important than press releases when it comes to public relations.
