Why Jekyll (Bootstrap)?
There are plenty of blogging platforms available, from microblogging platforms such as Tumblr to heavyweights like WordPress. Why use Jekyll?
If the idea of typing a post in your preferred text editor in Markdown (or
Textile), while using git to track changes and git push to deploy your site
sounds appealing then Jekyll might be for you.
Jekyll is a parsing engine that builds a static website by parsing your Markdown files and assembling the layout based on a template. There are no databases to set up and manage, and GitHub will host your site for free (using GitHub Pages).
The great thing about this setup is that you directly control the content in portable, flat text files. I've blogged on and off over the years on various platforms, and frankly I've lost track of many posts buried in random databases.
Most (if not all) security issues are eliminated by not using databases and server side scripting. There is no need need to constantly worry about logging in to an individually hosted WordPress blog to patch the most recent 0-day exploit.
Using static over dynamic pages also yields reliability and performance advantages. Traditional blogging software such as WordPress have to use a caching layer to serve static content.
To clarify, Jekyll is not a blogging software. It is minimalistic and efficient at generating static web sites from Markdown and template files. The drawback is you have to code all the front end templates from scratch. However, this is where Jekyll Bootstrap comes in.
Jekyll Bootstrap builds on top of Jekyll by adding modular theming, default templates, and other niceties such as Google Analytics, and Disqus commenting. By following the front page directions you can have a blog up in ~5 minutes.
