If you’re still unsure about the new WordPress Editor (aka Gutenberg), it’s worth watching Matt Mullenweg’s State of the Word keynote at the recent WordCamp US 2018 event in Nashville.
You can find links to parts of the talk, along with slides, and commentary in Matt’s post, here:
I’ve been using the new Editor almost exclusively lately, not because I work for Automattic, but because it’s actually a pretty enjoyable way to write posts.
I still prefer to write longer posts in my text editor, and then add the posts into the editor afterwards (I’ve always been a little twitchy about my only version of long posts being in an online editor, just in case something goes pear shaped and I lose it all).
The new Editor isn’t perfect, but it’s pretty good! It does work a little differently in some respects, but that isn’t a bad thing (necessarily). Also, it’s improving (I can add galleries that work the way they’re supposed to! Yay!) all the time.
