With all the posts on HN about paid personal knowledge bases like Roam I'm excited to see a free and open one leveraging my favorite editor.
It does have the emacs string attached but I've been using doom emacs with it (for vim keybindings) and the learning curve is 100% worth it. 3 weeks in and I haven't looked back here.
It's such a nice piece of code, and the author and community are fantastic. Asking for help is encouraged, as is sharing your modifications to the standard workflow.
It's also actively developed, and as such new features are frequently popping up.
