What People Are Saying
I'm using @logseq + @obsdmd! Logseq is an outliner + task management that works well with my "18,000 things at once" daily way of thinking. It's also connected to Obsidian, where I keep my longer term research that benefits from structured documents.

Freaking *loving* @logseq since I started using it on the desktop.

Mashup of roam and org-mode's task management is making me very happy so far, even in 0.0.13. Super impressed as giving me all the things I like about roam, emacs org-mode, and notion together. ♥️
Every time I use @logseq I'm thinking, I needed this years ago. And the gleefully look at a future where I had this for years.

shout out to @logseq if you haven't tried it! It is the best of Roam and Obsidian, in a format you are probably very used to already. Great community, amazing approachable devs, lightning fast development. Free, local, privacy focussed, outliner.

Ok, I'm having an absolute BLAST using @logseq for my DevLog and Tech notes that need more structure and organization.
