Did you ever get a response to this? I have a project under development that might be able to do this for you. It's a general reporting solution that lets you write reports against drupal and other databases. If you haven't got what you needed any other way. File a quick feature request at:
http://drupal.org/project/forena
I should be able to do this pretty quickly.

Good morning,
Is there a way to create a monthly report that would tell me how often our web editors are publishing either new or modified content?
Thanks,
Leslie
