It isn't just about Drupal here at ActiveLAMP -- when the right project comes along that diverges from the usual demands of content management, we get to use other cool technologies to satisfy more exotic requirements. Last year we had a project that presented us with the opportunity to broaden our arsenal beyond the Drupal toolbox. Basically, we had to build a website which handles a growing amount of vetted content coming in from the site's community and 2 external sources, and the whole catalog is available through the use of a rich search tool and also through a RESTful web service which other of our client's partners can use to search for content to display on their respective websites.
