Here at Avatar New York, we frequently use the open source Content Management System (CMS), Drupal, to build most of our content heavy websites.  In my opinion it's one of the best CMS's out there.  With that being said, it still has a few quirks.  One of my complaints is that it doesn't have a whole lot of SEO features built into the core (although it does provide for search engine friendly URL's via mod_rewrite).
