I've been using wordpress for more than a decade now and if you have multiple sites like me, you know the bloat that comes with it. Endless plugin management, themes, conflicts.
The core of Wordpress (aka the articles) usually gets lost and I have been on a quest for something that would simply let me focus on publishing.
This is it. It's actually more powerful and undersold. Reading the description, you think this thing is a plugin to manage your post. Nah. It's a complete CMS, and if you get the max 3 codes, you basically have all the blogs you want (up to the million views per month).
I'm hoping for some more controls over the appearance in the future as this is obviously something that I need to send my developer to do.

If you want the TLDR, this is an LTD blog platform with all the bells and whistles of something like Substack. With the right developer (Just look at the Gen-zine example) this is crazy powerful. I can only hope for more user-friendly site level editing in the future.
