WordPress is web software you can use to create a beautiful website or blog. They like to say that WordPress is both free and priceless at the same time. See http://wordpress.org/ for details.

WordPress uses plugins to provide customisable functionality, including RootsPersona which takes a Gedcom import and automatically presents a series of linked individual pages and a pedigree. A full list of genealogy plugins for WordPress can be found here.
