Speaking of Gutenberg, you can download the Gutenberg plugin from the plugin repo as well and try it out yourself.
Some are already sharing their first impressions. Matt Cromwell notes it’s flexible, but also mentions some weaknesses and concerns. Chris Lema states that he “clearly missed the goal of this thing”. Finally, as Aaron Jorbin points out, that this really isn’t even currently a beta and plenty will change between now and any possible inclusion in WordPress core.
Gutenberg shows a lot of promise, and I’m happy to see a working prototype. This is the kind of experimentation WordPress definitely needs. It’s also good to see people trying it and sharing feedback. I (Brian now) plan to do the same.
