This should be great news, but I decided to use Gutenberg on a friend's very simple site a few days ago and hit nothing but errors. "This block has crashed" (or whatever the phrasing of the message is) it has failed/ is unrecoverable / something.

The content of the page and whatever was being edited (text, gallery, etc) was regularly replaced with a grey "crashed block" error box. In that case there is no remedial action activated, presented, or apparent in the error box and process. Fortunately I know about post revisions and where to find them - and so was able to (regularly) reclaim the uncorrupted post versions. This seems bad to me.

What was I doing? I was entering galleries and basic text and headers on a brand new empty site. The theme was a simple well known cutdown framework and the only othe plugin was Woocommerce. Gutenberg crashed a block and I had to revert to a revision somewhere around 3 times within ten minutes. It was very infuriating.

Now, whats my aptitude level? Reasonably adept, as I write plugins for WP and I've been working with WP CPTs, API and CLI for many years. I'm up to date with eveything Gutenberg and I've followed and contributed (words) on the repo since Gutenberg was first announced. Regarding the WP editing experience and of editing posts I'm "an expert" compared to a general or new user.

What's my stance on Gutenberg? Am I a "hater"?
I desperately want Gutenberg to succeed because of my vested interests in supplying easy intuitive solutions to my clients.

So, if my experience was profoundly negative due to the crashing and instability I'm very interested to see how general users respond. My suspicion is that the outcome will be bafflement and disappointment.

I wish these issues had been resolved before laying it in front of the general public as a finished product to try. You only get one chance to make that vital first impression. I hope the plugin becomes more stable before eventual release.

I will of course try to document these issues on github when I get chance.
