Pretty cool. I do default to SQLite these days simply because I can just put it on the host, set up a PVC to it, and run the app in Kube pointing at a persistent SQLite. Absent some other need (it's a fork of psql- or mysql-based software) I prefer using it for simplicity.
I do have to say that I've found lobste.rs generally a pretty slow site to render and navigate and I wonder whether that's the Rails backend, or underpowered hardware, or lack of caching. It's more feature-ful than a HN or Reddit though with much lower usage so I wonder what it is.
