Time to update that list of open source software shops specializing in nonprofit/advocacy/political work — June of 2007 was a while ago. The companies assembled below all work with open source software and nonprofits or campaigns in some way, often pairing Drupal, WordPress or Joomla expertise with other services like communications consulting. For instance, a certain Epolitics.com focuses on internet advocacy strategy and training for clients but also does design and templating (and some technology) in Drupal and WordPress.
Developments since the first round? Primarily, the appearance of a lot more players distributed around the country, suggesting a healthy ecosystem of nonprofit clients (though inevitably a couple of firms seem to have disappeared, too). Also, slowly but steadily Drupal seems to be winning out over Joomla (food fight!), with WordPress a solid presence at the lower end.
But wait, there’s more! Help build this list by suggesting other companies. Better still, add gossip, innuendo or even solid information about anyone below. Operators are standing by! (I.e., please leave your contribution as a comment). Thanks!
