Minor correction, I don't think Datomic is used. I believe it uses a variation of DataScript and in turn DataLog for queries. Whereas Datomic is a DB which is also based on and uses DataLog queries.

Either way, super powerful.

It's great, but I wish there was some more interesting stuff you could do with the results of that query, other than show an outline or table.

The inline programmability of DataView and the Grid views etc are pretty killer. Unfortunately Obsidian is not for me, so I hope Logseq catches up.
