This question came up the other day about simple open-source content management systems (CMSs).
"What are the best simple, open source CMSs for small, content-oriented sites?
Something relatively simple and easy to modify, and with a good facility for editing articles (not just blogging). Textpattern might be one example. What others?"
Questions about CMSs usually come up in the early stages of a web project, web development clients often ask questions about managing their own content. Here are some helpful guidelines about picking the content management systems that meet your specific needs and some helpful resources for additional information.
When you say content oriented, do you mean outward content like (1) blog articles or (2) more rich types of media content or (3) content in the form of documents?
(1) Blog articles and other outward facing text content for a small, low traffic site: I would think about WordPress, Concrete5 / same content larger, higher traffic site: Drupal, Umbraco, DotNetNuke, or Joomla
(2) Media, photos, social content: probably LifeRay
(3) Document management: Alfresco
