Third Alien Shore is powered by WordPress, the state-of-the-art semantic personal publishing platform. Not only is it powerful and easy to install, but it’s open-source and completely free.
The site design template is called Thematic, by ThemeShaper. Although I’ve modified the template somewhat, I’m very grateful to ThemeShaper for making it available.
The body text is set in Source Serif Pro, created by Frank Grießhammer at Adobe. The titles are set in Source Sans Pro, created by Paul D. Hunt at Adobe. Source Serif Pro and Source Sans Pro are available for free via the Open Font License 1.1.
