Currently I’m using Joplin with Syncthing-backed file system synchronization. I’m pretty pleased with it, as I do like tagging- and Markdown-based systems.
I plan to upgrade to server-based synchronization, but before doing that, however, I wanted to see what other people are using.
Edit: So far I see a slight favor towards Joplin and Logseq, but I totally didn’t expect (and appreciate) getting so many different answers.
Just tried it for a bit. Looks pretty sleek and has some nice features, but it seems like it’s not open-source, which is something I’d like to avoid.
Then Logseq. It’s an outliner (each line can be it’s own…thing…), but it’s open source and a direct competitor of Obsidian. In fact, I was ambivalent between the two when I first started with online note-taking.
That looks very interesting, mostly because it’s so different. I’ll have to take a closer look later.
I am not trying to defend Obsidian here in regards to its closed source but in the least the notes are not obscured in some database and use markdown format. So once they go away from that, I am out and still have all my notes accessible.
