In general, WordPress is best for a site that uses static pages and single, regularly recurring content type (e.g. News or a Blog post) - it rocks for this purpose.
With the addition of a few basic plugins, we like WordPress because it provides excellent scalability and SEO potential.
A few of the benefits of using WordPress:
- Social publishing and collaboration
- Cross-blog communication tools
- Workflow management
- Customizable theming
- Multiple authors
- Plugin and Widget custom development
