Hugo, and static site generators in general, are amazing. Not only are they extremely fast and more secure than CMS-based solutions, they can also be easily cached and distributed worldwide — making them accessible to a global audience without much effort.
Hugo itself sports a large and fast-growing theme gallery full of inspiration. Even without any prior Go experience I was able to create my own custom theme in a matter of days — and had a ton of fun doing it.
For those just getting started with static site generators, use Jekyll to learn the ropes then Choose Hugo over Jekyll once you get the hang of things.
