Played around myself for a bit. It’s an interesting concept — seems somewhat specific (not overly so) to the designer’s preferences. I don’t fault the owner or the beta being unpolished, and will keep my eye on Roam Research. Preferably, it would store documents locally with the cloud as an option, otherwise I don’t see using it for anything much.
