Welcome to billbreitmayer.com. Currently, this is site offers three categories of subject matter, collected into three different areas. Each has a different perspective or content format.

1 - This area ( "Home" ) presents overviews of the site, plans for the future, general areas of interest and, not least, summaries of my professional history and experience.
A note about the "Recent Changes" pages. They describe major changes to the content of this site or to the Drupal Content Management System driving it. In other words, it's not a change log for site content, but rather lists the big changes either in the structure of the content or how it is delivered by the CMS.
As of mid-June 2007:
The three primary subject areas are Business Rules, Rules Based Systems and a new section for the Semantic Web that is still being written. At the moment, the Home site is somewhere between an index into the static content of the old Tutorial and a PHP content management system. There's a mixture of old and new.
As of June 12th 2007:
First, the task of importing the old "Tutorial" content into the new Drupal Content Management System is still progressing slowly, but at an accelerating pace ( that is accelerating progress, not accelerating slowness, which is the usual state of affairs ).
