Hi Internet,
I know it's a bit late but better than never. Several Days ago I went to the Vancouver Drupal User Group March Meeting. I had a good time! My main objective of course was to network but I really learned quite a bit about how I can increase efficiency on my Drupal site deployment as well ways to reuse parts of older projects with some development tools.
The presentation topic was Reusable & Deployable Drupal Sites with Shawn Price. It was very informative and very technical. The bread and butter was all about how to do things well once, and only once. The techniques used Drush heavily and involved the Features Module and Install profiles. To avoid breaking the DRY rule he showed us the advantage of keeping a basic drupal installation profile as well as a set of features for any occasion.
