Wow! Im am thuroughly impressed with Jekyll and how easy it is to put together. It's incredible! I come from a Wordpress background. I've been toying around with Wordpress for the last 6 or seven years and, like most people, was my go to CMS for putting together a website.
Over the years, however, as the system expanded it became very clunky. It can do a lot and is extremely extendable but that comes at a cost, lots of code. A lots of code.
