There are 450,000 installations of Gutenberg, according to Gutenstats.blog, which is a count of the WP.com sites that have activated Gutenberg and of self-hosted sites that have Jetpack installed and have activated Gutenberg.
The site also lists the number of posts written. The count started in late August 2018, and when I looked at the stats just now it said that over 250,000 posts have been written and that 6,264 posts were written yesterday.
The number of posts does not include those on self-hosted sites that have Jetpack activated. That’s because Jetpack doesn’t ping WordPress.com when a new post is written.
And it does not include posts on self-hosted sites that do not have Jetpack activated.
On my self-hosted sites I’ve written around 40 posts using Gutenberg, so multiply that number (and more) by the number who have it installed on their self-hosted sites and it’s easy to see that the actual post count will be much higher.
By the way, I saw this info in an email Matteo Duò from Codeable. You can sign up for articles on Gutenberg by going to Get Ready For Gutenberg on the Codeable site.
I have to smile. Gutenberg has this giant test bed of WordPress.com users giving it running feedback. And there is more feedback from thousands of self-hosted users who are using it and breaking bits of it and reporting the issues.
If my memory serves me correctly, this sculpture is on the stairway of the Historical Art Museum in Vienna.
I don’t know who the parties are, or the sculptor (oh how time runs on when one is intent on getting somewhere else) but it might show the centaur Nessus being killed by Heracles.
The poignancy in the sculpture is that the centaur’s tainted blood in turn killed Heracles.
Alternatively, the sculpture shows Gutenberg slaying the old WordPress editor.
Caxton
Gutenberg (as in Johannes Gutenberg) died in 1468.
William Caxton was an English merchant who worked in Europe and who in 1476 moved back to England and introduced the printing press into his home country and was the first English retailer of printed books.
If you are English you learn about him in school.
I mention it because PootlePress have introduced a plugin of additional Gutenberg blocks for sites running WooCommerce on WordPress and using the Storefront theme. They have named their blocks Caxton.
