Pretty cool!

Tried it out for 15 mins and it seems like a useful tool to replace organisational tools like Notion. As I understand it; It synchronizes its data between devices peer to peer on local networks with the option to back up to a server if needed.

Way better than other alternatives in a privacy perspective. The user experience was a little rough imo though. Very many details and the graph view was rather cluttery. It had the option to toggle some information off in the graph view, but I couldn't really find a good setting that was both informative and not cluttered. Also, there were very many different types of views that were nested in each other when viewing pages. This confused me a little, but may become clearer if used for longer than 15 minutes.

All in all; I love this type of technology. I will likely use this instead of Notion for the few projects I have.

This has been my initial thoughts. Not a complete review. Try it out yourself! They have very good packaging alternatives.

I think I missed it on their site. Can someone point me to how I can host a local server as a container on my homelab?

This would be really nice on something like the pi. As I don't have a "real2 Linux server, just a desktop that's my main machine, but its off when not in use. Bit impractical for running this.

It looks like they are planning for some services that will let people contribute publicly... How will moderation work?

The way it's written sounds like the answer will be "it won't" - which would mean it will very quickly become a Nazi bar (think Voat or 4chan)
