Drupal 7 release is close, not too close ofcourse Drupal's community still has a long way to go. Too many awesome feature included in Drupal 7 require quite some polishing.
But i think it's time to start planning for Upgrading our Drupal 5 site to Drupal 6. I only have one site left with Drupal 5 , it didn't worth upgrading before but today after i used upgrade status to see the status of the contrinbute moduels i used on this site, they've either upgraded , included in Drupal 6 or replaced by better alternatives.
