Joomla, Drupal, Wordpress, or ExpressionEngine?
byoung2: That's a difficult question to answer without knowing what content you're going to put on the site.For a simple 5 page site + blog with frequent updates, I'd say Wordpress.  There are lots of plugins and templates are very easy.  It's the only blogging software I'd recommend for a basic blog.For a site with a lot more content, Drupal is a more robust option.  It's really easy to expand with modules for blog, forum, shopping cart, etc.  I find the template system more confusing than Wordpress.
