drush tutorial

This blog post shows off some great new ways Drush 3.0 is better than earlier releases. http://developmentseed.org/blog/2010/mar/10/drush-30-more-powerful-flexi...

It's a good read to get ready for updating to the next level of Drush's Drupal power.

hi, i guess im still a beginner in drush as i dont really use all the commands. i haven't gotten to use devel yet as i dont see the usefulness of it yet.

but as for drush, ill share my experience with how i use it. i have a multi-site drupal code base and drush is a lifesaver having to enable, disable, and updatedb for each site. im maintaining about 5 sites now and all i use drush for is just enabling and disabling modules mainly.

Is there something else i might be missing that everyone uses frequently? like deleting users or nodes or what not?
