Yeah I’ve really loved the culture of niche instances like startrek.website, lebowski.social, sffa.alliance. I think they provide an interesting and friendly local feed, have a more general federated feed, and then of course you can have your own subs. I say go for it!
Wasn’t self-hosting but trying it out with their server for awhile. I think the idea is great, and I think one of its big UI advantages is it’s a lot more intuitive on mobile than most other personal knowledge management / note takers I’ve used.
I did find it pretty buggy at times and a lot of the features not built out enough yet to be a daily driver for any particular use case of mine yet. I’ve tucked away into my “cool projects to check up on at a later date” mental drawer.
