I've been using Gutenberg on my blog recently to gain some familiarity with it. There are some things about it that irritate me (such as the HTML code it produces), but overall, for what it is -- a distraction-light writing experience -- it's not terrible if all you're doing is writing blog posts.

I feel like there's almost the core of a good idea here that's being misapplied. If Gutenberg turned into a really kick-ass front-end editor that could work for, say, 90% of blogging cases, while the current editor in the admin stayed intact (for the other 10% of blogging cases as well as all of the non-blogging cases), that would be the ideal. But if Gutenberg is intended to be admin-facing, then it's the wrong solution to the wrong problem, imho.
