I just finished a site they commisioned me to port to Jekyll from WordPress ([0], live version at [1]). And though I wasn't much happy about how Liquid makes the layout templating look dirtier quickly I still understand why static generators were a great idea and offer much more flexibility and reliability than WP - and to be honest I prefer Liquid's mess than PHP's mess.
Granted, at least Jekyll was conceived as a blogging system and quickly falls short when needing to do a bit more complicated stuff (like having multiple sections of content from a single Markdown file [2]), and alas it seems it's struggling to keep in pace with the numerous competitors it has now.
Jekyll has a fork called Bridgetown which is, granted, a little more complicated. If you like Ruby but want a more fully-featured site generator there's Middleman which I highly recommend.
