@flancian @neil nice to meet you too!
I was curious about Foam, but I've only used VS once, so ended up giving Obsidian a try & liked it. I got the sense its MD wasn't great for [[wikilinks]]?
The bridge from Obsidian to something that's public and css-able is my current puzzle (slow as I'm new to SSG & Gitlab/hub Pages). It sounds like what you are saying is so long as whatever is generated from that is markdown it should be ok to go into agora? But not something single-file like TiddlyWiki?
