Additionally, WordPress offers a multisite function that allows organizations and institutions to manage networks of sites managed by separate individual site owners, but centrally administered by the parent organization. You can also expand WordPress into a social networking or community site, forums, etc.
The same scalability applies to web design. You can start with a simple design and then scale things up to display sites with amazing visual features, including animations and video effects, sliding images and animated product image galleries, elements that appear and fade from visitor browsers, etc.
The scaling possibilities of WordPress are truly endless.
