Its time for my quarterly analysis of Amazon stats for Plone books. Of particular interest is that Aspeli has "dropped" from around 50,000 to well over 200,000. Remember that increasing Amazon rank means decreased sales volume.
With this sudden up-turn, I'd be inclined to think that six months after the Plone 3.0 release and the publication of Professional Plone Development everyone who needed the book has bought it.
Come back in Sept. and we'll see if this is a fluke or a continuing trend. For prospective authors, now is the time to hit the market since there's room at the top. Better still, how 'bout a second edition, Martin? Geared to 3.2?
