I decided to finally install the Gutenberg plugin. I have read a few posts (Jeff Everhart and John Johnston) and realised that I probably should have a look.
My first impression was that it felt like the WordPress.com editor. I can see the appeal of blocks, it works for the new Google Sites and Weebly, but fear that it is overkill for what I do? I also noticed that Post Kinds disappeared.
Interestingly, in the screen providing a summary of all the posts, there is an option for starting a new post in the Gutenberg editor or the classic editor. Maybe this choice is an eye to the future, just wonder if there is a means of making ‘classic’ as default?

Some other reflections:

Dear the WordPress. You know I love you like family. But I am testing Gutenberg with Jaws right now and we really need to have an honest discussion about where this is going, including discussions from the other concerned developers.

but sure, I’m going around everywhere claiming/complaining. What I have said is, IF the goal is to compete, acknowledge it and move on.
I’ve also said Gutenberg feels like skating to where the puck is, not where it’s going.
But never have I called out an individual.
