This is very cool, and I've been watching the project for a month or so.
I like the query setup and the templates look very interesting. One of my biggest complaints about Logseq is how much of a pain simple query operations can be.
A few things make me hesitate a bit:
I've been burned on single-dev passion projects in the past.
As a self hosted web app, it's a bit more difficult to manage on a company owned machine. I know Electron apps get hate, but that would ease some pain here.
The rapid pace of development is both exciting and worrisome. For example, a recent update completely changed the underlying templating engine from a well-known open source solution to a custom solution. I worry if I rely on this, something might catch me by surprise.
