It is FOSS, to begin with.

And it is built around back links, making them more useful, in my opinion.

Instead of linking in a wiki style, you link in a tag style, to collect blocks together. Then, when visiting the linked page all of them are together and editable.

They suggest you write everything in the daily notes, then link from them. Except for the end result Markdown, it aligns with how I think.

Theres also checklist automation, and tagging days in the future for reminders.
