Lullabot (Angie Byron): "A "distribution" of Drupal is one or more installation profiles included with Drupal itself and all of the required modules. Distributions can either be offered as a convenience to site builders by bundling together frequently used components, such as Acquia Drupal, or they can be used to offer a version of Drupal specifically targeted to a unique use case, such as Open Publish. Dries has some heavy things to think about for anyone interested in getting into the distribution business, so I'll pause for a moment while you go and read that link.
Back? Great! So you've decided you want to share your ultimate Drupal site for whatever reason, and you want to do it in the fastest way possible. Then this article is for you!"
