I’m using Jekyll to manage all content on this site. It’s not hip, but it’s simple and does the job.
Same with Bootstrap for CSS. I like it because it takes care of most of the hassle of making CSS look nice enough in any browser, so I can worry about the other details.
Font Awesome is a huge, free collection of vector-based icons. The social media icons on this site come from the collection.
The font used for the site is Source Sans Pro by Paul D. Hunt, via Google Fonts.
