I primarily use Logseq because I've found that outliners best align with my mental model. I mainly take notes within my daily journal. When I encounter something worth saving, I simply create a new entry. A typical day looks like this: https://i.imgur.com/wAiYgSY.png

To categorize the information, I simply link the entry to a specific page. For example, if I discover an interesting React library, I create a new entry like this: https://i.imgur.com/dDlStkZ.png

A great feature is that Logseq understands page hierarchies, so if I click on [[Dev/JS]], it presents a clear hierarchical overview: https://i.imgur.com/z9hGmmh.png

Using this approach, I've stopped bookmarking sites in my browser altogether. In Logseq, I can connect useful things to each other, add entire notes, and more, as shown here: https://i.imgur.com/Krld2cS.png

If I want to remember something, I just add a #card tag to the block, and it automatically syncs with Anki via a plugin.
