The [node:22630] says to post a message here if there are additional resources that would be useful. I maintain the Metatag module for Drupal 7 and it has supported the Twitter Cards since November 2012 - would you mind adding it to the list? I’m hoping to also add Twitter Cards support to the Nodewords module for Drupal 6 soon, so both of the supported releases of Drupal would have support for 'Cards. Thanks.
