Below is a list of my favorite Drupal modules and their availability of a stable/recommended version for the Drupal 7 platform. I merely assembled this information based on data from Drupal.org and I cannot provide recommendations based on personal experience with any of the modules. Modules in red are currently not available for Drupal 7 in a “recommended” release as of today (7/7/2011).
