i've only been using it for a little bit, but here goes:
* unlike Notion, it's one workspace per instance. makes sense, but worth noting as using workspaces as for organisational purposes won't work so well here.
* for personal instances, Slack doesn't make all that much sense. i see a PR for LDAP support on GitHub, so i will play around with that
* supports embeds just like Notion - paste the link and it just works. supports codepen, figma, gsuite, youtube and others. this was the feature that made me take notice of notion, so it's good to see it here.
* even better, the embed API seems pretty easily extensible, so the sky's the limit here. i can't wait to make some sweet dashboards based on entirely self-hosted data!
* no mobile app is a bit of a bummer, but the PWA experience works pretty well. considering i'll be authoring predominantly on desktop and only reading on iPhone, this isn't so much of a big deal for my use case
* no auto-save :(
* you can share a read-only, fully public link of any page you want. pretty damn cool.
all in all i'm pretty impressed. it seems pretty robust! i mean, it's definitely not as full-fat as Notion, but perhaps that's a good thing - and OSS means it's easily extensible for whatever you need to use it for. who knows which way my opinion will change after some more extensive use, but this definitely shows promise.
