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.
