Apart from the thread that exposes Sample Web Sites I want to open another one dedicated to GRAV experiences, the GRAV project deserves it.
A short summary: GRAV is already great for people with some basic knowledge on how to integrate websites and with some basic programming skills and there are only a few things missing to make GRAV a first choice for novice webmasters as well, e.g. people who want to set-up and run their own websites with nearly 0 knowledge at all.
I dealed with CMS for years, decades. I've worked with large scale enterprise solutions like Vignette, OpenCMS as well as with Drupal, Wordpress and Joomla. With all these systems I always felt that there's to much imposition, a sensation I never had with GRAV. I admit that this is a "vague" statement and probably GRAV benefits from being fresh and clean with no historical ties and burdens, but GRAV allowed me to work with a strong focus on my clients and their purposes and, important, with the feeling that I could even do big stuff with GRAV as well, that the skeleton is robust and fine.
I discovered GR AV at the end of November, 2016 when I was searching the web for flat cms'es, when two artists and friends asked for an easy while convincing solution to publish and maintain websites without "overkills". Getting familiar with the GRAV universe I soon found that there are still some minor "lagoons" that needed attention, e.g. an editor in conditions, but all this was relatively easy to integrate. 70% of the stuff I needed was ready for enhancement out of the box, through blueprints, available plugins and the already impressive set of themes existing. The greatest challenge (lagoon) was to provide a "What you see is what you mean"-editor (WYSIWYM), I decided to implement StackEdit and not a 100% Wysiwyg solution. StackEdit seems to me like offering the best out of both worlds: Markup and WYSIWYG. Once I had this solution operative I was ready to offer access to the artists. (One conclusion for me, GRAV should provide a convincing solution for editing out of the box and not as part of an expensive Admin Pro plugin. Admin Pro may include an even better editor but edition is crucial and the current solution is not promotable.)
This said: I invite everybody to help GRAV as a backer (https://opencollective.com/grav#support)
