We recently decided to move our blog off of Tumblr and into our main site. We wanted our blog to feel more like part of the main site and an integrated blog is also more SEO friendly. We thought about publishing our blog as static files with Jekyll. However, it quickly became clear that sharing our main HTML layout file between Jekyll and our main Rails app was not going to be elegant. The layout file needed to be duplicated, making it tedious to keep up to date.
