Yup! Notion also has tables that you can mix in with free-form text, but the formula language is not as robust as Coda’s.
I do indeed write elsewhere but plan on writing under the Coda publication more regularly. As you saw from this post, I’m a big Excel user and have a blog that goes back a few years on my adventures in Excel. I also haphazardly update a random blog about my favorite places to eat chicken :).
