I recently demonstrated how easy it is to manange content with Drupal.  The discussion eventually drifted from content management to content creation and the  importantance of text versus graphics.  Not only do you want to write for visitors, but for search engine optimization (SEO).  The AddMe newsletter offered an excellent article on this very subject.  It's called  Good Content and Good Copy = Good SEO
The author, Zachary Elwood, not only offers tips on writing good content, he offers ways to work with search engines such as google.  It's a very good read.
