Our Big in Japan tools, specifically PodServe, have seen a huge spike in usage recently.  It is becoming clear much of the current traffic is due to a single podcast.  Leo Laporte covered PodServe on "Inside the Net" a couple of weeks ago and we thought it might help tell the Big in Japan story to 15,000 people (the number of listeners Amber Mac reported to us).  

Evidently Leo's podcasts (according to AOL Radio who distributes them) are more popular than we thought.  In March alone Leo had more than 2.6 million downloads.  That is a big audience by any measure.  As a result traffic to PodServe has spiked, with registered users increasing by more than 50% since the interview.  

Leo, like PodServe, targets a very specific niche firmly planted in the long tail.  Alex blogged about how it is very inexpensive to reach these long tail markets in a post titled, "Biggest Market = Highest Cost to Reach" earlier this week.
