It's taken a very long time to get to this point, but my paper on the Soccer Pythagorean has been published in the recent edition of the Journal of Quantitative Analysis in Sports. You can find a link to the paper here.
Thanks to all who helped bring this about, and it is my hope and expectation that this will be the first of many journal publications from Soccermetrics.
UPDATE: There is a Guest Access feature of the journal that allows readers to view the article at no charge. If you would rather not bother with that, send me an email to hhamilton -at- soccermetrics -dot- net and I will send you a copy. But I do suggest that you go through the JQAS website, as downloads from there are credited to my publication ranking.
UPDATE #2: I just found out that my paper is currently listed as the most popular JQAS publication so far in 2011. Still a long way to go in the year but I am amazed. Thank you so much!
