Quarterly Amazon Sales Rank Stats

It's time for me to pull myself away from the Herculean task of emptying out my parents' house and get back to our regularly scheduled program.  It's the beginning of the quarter when I usually take a moment to see how Plone titles are faring over at Amazon.com.  Here's the latest sales rank statistics for Plone texts: 

From the zigs and zags you can see that Amazon sales ranks, as always, aren't very stable.  Julie Meloni's "Plone Content Management Essentials" took a huge leap.  (Remember low sales ranks is a good thing.)  And in fact, just about all Plone texts improved their sales ranks.  Four books have sales ranks below 200,000 and only three had their rank go upwards (Rose, Cooper, Lotze and Theune).  Frankly, I'd have to say this trend, if it continues, could indicate a healthy turn of affairs just in time for Plone 4.
