Announcing the Drupal Showcase at showcase.acquia.com
It's always feast or famine. During Drupal's first few years, core contributors all knew when a new Drupal site launched, and usually also knew the people who created it.
There's simply no way to keep up. Acquia runs a site crawler to find new Drupal sites, there's a forum and wiki on Drupal.org, and individual efforts like drupalsites.net and the collection on my own blog list sites as well. Still, I think we've all been face-to-face with someone who asks, "Who in my industry runs Drupal?"
So a few months ago, we started a project at Acquia to collect, curate, and tag some of the most-impressive sites in Drupal that we could find. The result is the Drupal Showcase. We've categorized them in several ways and accompanied every listing with a screen shot, description, and link. Just as importantly, we've highlighted some of the biggest and best-recognized brands so that anyone you send to that page immediately understands that Drupal is succeeding in the major leagues.
We collected sites using the crawler that I started in 2006 and that was fully realized recently by Marc Seeger as part of his Master's thesis. Rob Loach led development of the Showcase site, which was then populated by staffers, partners, and interns Olivia Holmes and EB Pruett. They manually went through the enormous collection the crawler found to glean needles of gold from that haystack. We plan to add new sites every week, and welcome you to submit your own site for consideration: Just register, then click "Add a site".
By the way, Rob built the Showcase using Drupal Gardens, the free Drupal-based site-building platform Acquia runs. It's a good idea to "eat your own dog food" once in a while; this project showed us that it tastes pretty good.
I hope you find the Drupal Showcase useful in for promoting Drupal, and for helping prospective users see that others in their fields have been successful with it.
