Oh I can actually answer something, neat.
I thought I was missing the appeal too, but when I got back into tabletop roleplaying games, a lot of the community is located over on Substack blogs, and I don't like Substack. My solution was to start running FreshRSS and put all of the feeds into it so I could read at my own pace, and also not have to go to a million sites to keep track of content. Saves me a lot of tabs in an internet browser, if nothing else.
Sadly, not all sites or blogs have RSS feeds to hand out, but I've used https://openrss.org/ to get around that for the most part if they don't.
First, thank you much for suggesting BookOrbit! I actually just installed it because I was having a lot of issues with Grimmory making dupes of books in every folder and couldn't figure out why it was doing it. Haven't had any issues with BookOrbit and I really like that it's got achievements. Plus, the less RAM usage is nice.
I'm using docker and docker compose files! Thank you for answering, the last time I took a crack at selfhosting, I really felt lost and screwed a lot up, so I wasn't sure if that was even possible.
