I am going to slightly eat crow on this one and say that Obsidian is awesome. Onus is on the user to figure out syncing and I do wish they were fully open-source, but I fully understand people wanting to protect their right to earn a living off something amazing they have built.
The productivity benefits from the open file format and extensibility via plug-ins and templates, combined with good UI is undeniable. nostr:note1x7q9t9k6z79mfmr25mffz9205aeezhqush79pcwky566v92hafwsmlm3ay
