Each year, Packt Publishing conducts a competition to determine the top open source content management system. Nominations are accepted from the general public for several weeks, then tabulated to determine the top 5 in each of several categories - Best Overall, Most Promising, Best PHP and Best Other. New this year was a Hall of Fame award for previous winners in the Best Overall category.
