For what it’s worth, I played with it literally a couple of days ago. I found the set up very easy, the themes limited but decent, the functionality around creating posts and pages very fast and clean. It also has cross-posting to LinkedIn, Twitter, Facebook, and Medium built-in. I also found that $5/mo is perfectly acceptable - many blogs charge more. I absolutely loved that you could enable a GitHub Pages integration, de facto backing up your website for free.
On the con side, there are things you can’t customize (eg their default footer that says to follow the user, or their archive page), search is only present in some themes and also can’t be customized, and there is very limited information about the project overall. The lack of ability to add an option for email subscription also is a significant issue in my opinion.
I was investigating the project from a blogging point of view and concluded it is trying to be Twitter first and foremost so not a good fit. Still, it was a pleasure to discover something new, interesting, and reasonably clean and functional.
